Available in PDF, EPUB and Kindle. Book excerpt: Due to high demand for planar structures with low loss, a considerable amount of research has been done to the design of substrate integrated waveguide (SIW) components in the mm-wave and microwave range. SIW has many advantages in comparison to conventional waveguides and microstrip lines, such as compact and planar structure, ease of fabrication, low radiation loss, high power handling ability and low cost which makes it a very promising technology for current and future systems operating in K-band and above. Therefore, all the work presented in this dissertation focuses on SIW technology. Five di erent antenna systems are proposed to verify the advantages of using SIW technology. First, a novel K-band end- re SIW circularly polarized (CP) antenna system on a single layer printed-circuit board is proposed. A high gain SIW H-plane horn and a Vivaldi antenna are developed to produce two orthogonal polarizations in the plane of the substrate. CP antennas have become very popular because of their unique characteristics and their applications in satellites, radars and wireless communications. Second, a K-band front-end system for tracking applications is presented. The circuit comprises an antenna array of two Vivaldi antennas, a frequency-selective power combiner, and two frequency-selective SIW crossovers, which eliminate the need for subsequent ltering. The integration of monopulse systems in planar, printed circuit SIW technology combined with the added bene ts of ltering functions is of great importance to the antennas and propagation community. Third, a phased array antenna system consisting of 24 radiating element is designed as feed system for reflector antennas in radio astronomy applications. A Ku-band antipodal dipole antenna with wide bandwidth, low cross-polarization and wide beamwidth is suggested as the radiating element. Forth, four di erent right-angled power dividers including in-phase and out-of-phase dividers as feed systems for antenna arrays are introduced. TE10 - to - TEq0 mode transducers are used for obtaining two, three, and four output dividers with phase control ability at K- and Ka-band. This feature is practical, for instance, when designing tracking systems since they are employed to obtain controllable phase distributions over the output ports. Fifth, a Ku-band beam steering antenna system which is applicable to use for wireless communications, radar systems, and also 5G applications is proposed. This antenna system uses variable reflection-type phase shifters which electrically steer the beam over a 50-degree scan range. Therefore, the SIW technology's reliability and also promising behavior in the microwave frequency range is proven for di erent applications.

This book was released on 2022-06-01 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Substrate integrated waveguide (SIW) is a new type of transmission line. It implements a waveguide on a piece of printed circuit board by emulating the side walls of the waveguide using two rows of metal posts. It inherits the merits both from the microstrip for compact size and easy integration, and from the waveguide for low radiation loss, and thus opens another door to design efficient microwave circuits and antennas at a low cost. This book presents a two-dimensional fullwave analysis method to investigate an SIW circuit composed of metal and dielectric posts. It combines the cylindrical eigenfunction expansion and the method of moments to avoid geometrical descritization of the posts. The method is presented step-by-step, with all the necessary formulations provided for a practitioner who wants to implement this method by himself. This book covers the SIW circuit printed on either homogeneous or inhomogeneous substrate, the microstrip-to-SIW transition and the speed-up technique for the simulation of symmetrical SIW circuits. Different types of SIW circuits are shown and simulated using the proposed method. In addition, several slot antennas and horn antennas fabricated using the SIW technology are also given.

This book was released on 2020-02-07 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Substrate integrated waveguide (SIW) technology is a twenty-first century transmission line that has evolved recently to open new doors to the development of efficient circuits and devices operating in the microwave and millimeter-wave frequency range. Microstrip circuits and devices are inefficient at high frequency applications and require very stringent manufacturing tolerances when used to implement microwave and millimeter-wave components. This is as a result of the fact that wavelengths are short at higher frequencies. Waveguide circuits and devices are preferred for higher frequency applications, but they are expensive and difficult to manufacture. It is also very challenging to integrate a waveguide device with planar devices in its vicinity. The SIW bridges the gap between the traditional air-filled waveguide and planar transmission lines such as microstrip. Practical Approach to Substrate Integrated Waveguide (SIW) Diplexer: Emerging Research and Opportunities is an essential reference source that discusses the development of efficient circuits and devices operating in the microwave and millimeter-wave frequency range through the use of substrate integrated waveguides. Featuring research on topics such as microstrip resonators, circuit model analysis, and quality factor extraction, this book is ideally designed for researchers, engineers, scientists, developers, scholars, practitioners, educators, policymakers, and students.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis we investigate substrate integrated waveguides and their application as a slotted waveguide antenna array. The standard slotted waveguide antenna is designed following Elliot's modified design procedure. Elliot's modified design procedure not only takes into account the effects of mutual coupling from the neighboring slots in the array but also the internal higher order modes that are scattered off adjacent slots. The antenna is then converted to a slotted substrate integrated waveguide antenna by carefully placing two rows of metallic via holes to simulate the sidewalls of the rectangular waveguide. The size and location of the via holes are calculated such that they contain the electromagnetic fields inside the substrate integrated waveguide with negligible leakage loss and that the substrate integrated waveguide has the same propagation constant and characteristic impedance as its equivalent rectangular waveguide. Integrating the waveguide into a substrate allows the entire circuit to be fabricated within the substrate and eliminates the need for complicated transitions that link a rectangular waveguide to a planar circuit. The antenna is fed by a 50? shielded stripline. The stripline is shielded by two rows of via holes placed symmetrically on each side of the trace of the stripline. The transition is composed of a single via hole that links the shielded stripline to the substrate integrated waveguide. Back-to-back transitions between a shielded stripline and a substrate integrated waveguide are designed and simulated for three different frequency bands; C band, Ku band & Ka band. The bandwidth of the transitions ranged from 20-35% in all cases. A back-to-back transition was fabricated for the C-band. The fabrication was done by hand using electrical tape for the stripline inner conductor and screws as the via holes. The bandwidth of the measured results show a smaller bandwidth compared to the simulated results. This disparity is due to the imperfections associated with fabricating the transition by hand. A uniform antenna array of 8 slots is designed and simulated with the feed network. A good radiation pattern with sidelobes 14dB below the main beam is observed. The antenna has an impedance bandwidth of 1GHz at the operating frequency of 15GHz.

This book was released on 2016 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, there has been increasing interest and rapid growth in millimeter wave (MMW) antennas and devices for use in diverse applications, services and technologies such as short-range communication, future mm-wave mobile communication for the fifth generation (5G) cellular networks, and sensor and imaging systems. Due to the corresponding smaller wavelength, mm-wave frequencies offer the advantage of physically smaller antennas and circuits as well as the availability of much wider bandwidth compared to microwave frequencies. It is important to design millimeter wave antennas with high gain characteristics due to their high sensitivity towards atmospheric absorption losses. Moreover, millimeter wave antennas can have wide bandwidth and are suitable for applications in large frequency range. In this thesis, planar antennas are designed using substrate integrated waveguide (SIW) technology to have low losses, high quality factor, and low fabrication cost. Firstly, an antipodal fermi linear tapered slot antenna (AFLSTA) with sine corrugations at the side edges at 32.5 GHz is presented, which has a wide impedance bandwidth greater than 30 %, in order to support the high data rate channels. This antenna has a high gain of 12.6 dB and low side lobe levels (better than - 17 dB) in both E and H planes. This antenna is studied and analyzed in array and beamforming configurations to meet requirements of millimeter wave applications. In order to obtain high gain and narrow beamwidth pattern, a 1 × 8 AFLTSA array using SIW power divider network is presented. The design characteristics of the power divider network are presented in this thesis, which help in calculating the performance characteristics of this array structure. This array has an acceptable bandwidth of 14.7 % (30-35 GHz) with high gain of 20.4 dB and 8.35° 3 dB beamwidth. The side lobe levels are also improved using this SIW power divider network and are lower than -25 dB in E-plane and -15 dB in H-plane respectively. This antenna has a radiation efficiency greater than 93% over the whole bandwidth. The second research theme is beamforming of AFLTSA antenna. This beamforming is performed using multi-beam antenna concept in which the beam is rotated with a help of compact beamforming network and excitation from different input ports. The design methodology for 2 × 2 and 4 × 4 subarray beamforming networks is presented along with their current distributions illustrating the beamforming process. These subarrays possess wide impedance bandwidth between 29-36 GHz. Moreover, these subarrays are able to achieve gain between 12-15 dB with narrow beamwidth reaching till 11°. All the results along with the numerical data is presented in this thesis. This antenna is suitable candidate for millimeter wave wireless communications and imaging systems.
