This book was released on 2011 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile communication has become an essential part of our daily life. We love the flexibility of wireless cell phones and even accept their lower quality of service when compared to wired links. Similarly, we are looking forward to the day that we can continue watching our favorite TV programs while travelling anywhere and everywhere including satellite channels and the wish list goes on. Mobility, flexibility, and portability are the themes of the next generation communication. Motivated and fascinated by such technology breakthroughs, this effort is geared towards enhancing the quality of wireless services and bringing mobile satellite reception one step closer to the market. On the other hand, phased array antennas are vital components for RADAR applications where the antenna is required to have certain scan capabilities. One of the main concerns in that perspective is how to avoid the potential of scan blindness in the required scan range. Targeting to achieve wideband wide-scan angle phased arrays free from any scan blindness our efforts is also geared. Conventionally, the key to lower the profile of the antenna is to use planar structures. In that perspective microstrip patch antennas have drawn the attention of antenna engineers since the 1970s due to their attractive features of being low profile, compact size, light weight, and amenable to low-cost PCB fabrication processes. However, patch elements are basically resonating at a single frequency, typically have

Available in PDF, EPUB and Kindle. Book excerpt: Overcoming a narrow bandwidth is an important issue in the design of low-profile cavity-backed slot antenna. In this dissertation, a versatile wideband circularly polarized cavity-backed slot antenna is presented. The structure demonstrates dual-resonance behavior, which can be tailored to provide a wide-band or a dual-band response. Circular polarization is generated with four feeds using sequential rotation technique. Polarization modulation is demonstrated by inverting the phase of the two feeds alone. The study presents and discuses antennas principle of operation, design procedure and realization using a standard economical printed circuit board (PCB) fabrication process. Measurement results indicate that an impedance and polarization bandwidth of 31.1% and> 47% respectively with symmetric radiation patterns in both principal planes can be achieved. Excellent polarization purity is obtained at boresight due to the feeding technique used; making the proposed antenna a suitable candidate in applications demanding high purity or for the use in an array environment. A two element antenna array is investigated demonstrating similar bandwidth as that of a single element along with improved radiation performance. Another advantage of the implemented feeding scheme is high isolation between the differential ports of the antenna, which is used to successfully decipher the unique signature of a chipless RF identification (RFID) tag.

Download or read book Design and Optimization of Dielectric Resonator Antenna Arrays Based on Substrate Integrated Waveguide Technology for Millimeter wave Applications written by Mona Sabry Abdalla Abousheishaa and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the lower frequency bands heavily crowded, the millimeter wave (MMW) frequency band has attracted a lot of attention, offering a wide range of applications. It also introduces new challenges to the research community. Antennas and MMW circuits with compact size, low cost, high efficiency, and low loss are much needed to meet the new requirements of these applications. This research focuses on the design and optimization of dielectric resonator antenna (DRA) arrays based on substrate integrated waveguide (SIW) technology, which has been proven to be promising for MMW applications. The objectives include both the development of highly efficient computer aided design and optimization techniques, and the development of new designs based on the SIW-DRA technology. Toward these objectives, an efficient and accurate circuit model is developed first. A previously reported structure of DRA array is investigated based on two different slot orientations. The total mutual coupling between antennas is firstly extracted and modeled as a two port S-parameters. Two different methods are used to extract the total mutual coupling due to the difference of the slot configurations. Next, a new and fully adjustable model for the mutual coupling is developed for DRA array, resulting in a flexible circuit model allowing the design parameters to be varied. A comparison with full wave simulation and measurement results proves that the circuit model can be used as an efficient design and optimization tool. The model is further verified through a new design of SIW-series fed DRA parasitic array, in which an additional parasitic DRA is added on both sides of each active element to improve the gain. The antennas are fed using longitudinal slots on SIW. Due to the configuration of the antenna elements, there is strong mutual coupling between the antenna elements. The good agreement between the electromagnetic (EM) simulated and circuit model results for this design further proves the efficiency of the model.Next, a new design of an eight-element SIW middle fed series rectangular DRA array with 45° linear polarization is developed. The implicit space mapping (ISM) technique is applied for the optimization of the complex structure. The new circuit model plays an important role in the optimization method serving as the coarse/surrogate mode, and a full wave solver is used as the fine model. Parameters in the surrogate model are divided into pre-assigned parameters and design parameters. In each iteration, the preassigned parameters are extracted so that the fine model and surrogate model outputs match. The design parameters are then re-optimized and fed to the fine model. As demonstrated with this DRA array design, the optimization approach combining the developed circuit model with ISM technique is highly efficient. Only three iterations are needed to reach an optimized solution for such a complex structure. The optimized design has been fabricated using a low cost Printed Circuit Board (PCB)-based technology for validation of both performance of the design and modeling techniques. The comparison between the simulated and the measured results shows very good agreement.
