Book excerpt: This project will focus on the application of advanced electromagnetic simulation software 4NEC2 for the far-field characterization of a 3-element K-band array of waveguide antenna. Previous modeling efforts have shown a significant difference between simulated and measured data. The key effort in this project will be to minimize the difference between simulated and measured data by use of the 4NEC2 software. The simulation will be carried out on both a 3-element array of open-ended waveguides. The main application of these arrays in the far-field is in satellite K-band applications, where we would require multiple beams that can be controlled in beamwidth and position. The conformal nature of the array described in this work has the ability to control the beam positions and beamwidth by adjusting the conformal nature of the array.

Available in PDF, EPUB and Kindle. Book excerpt: This book is designed for both the scientific audience, research and development engineers and the university students. The fundamentals of radio frequency antenna beam forming is explained in this book. The principles of beam focusing and beam steering in near field and far field are visualized with 2D and 3D simulations and compared with measurement results. Besides linear and planar antenna arrays, also conformal arrays, i.e. concave and convex antenna arrays, suitable for certain applications, are investigated and presented. Also related applications of radio frequency beam forming like open loop and closed loop large scale antenna arrays or massive MIMO, which is one of the break-through technologies for 5G and future 6G and involves an extremely large number of antenna elements for the multi-user beam forming, as well as thinned antenna arrays with electrically large distances between the antenna elements are discussed.

This book was released on 2021-10-20 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced Antenna Array Engineering for 6G and Beyond Wireless Communications Reviews advances in the design and deployment of antenna arrays for future generations of wireless communication systems, offering new solutions for the telecommunications industry Advanced Antenna Array Engineering for 6G and Beyond Wireless Communications addresses the challenges in designing and deploying antennas and antenna arrays which deliver 6G and beyond performance with high energy efficiency and possess the capability of being immune to interference caused by different systems mounted on the same platforms. This timely and authoritative volume presents innovative solutions for developing integrated communications networks of high-gain, individually-scannable, multi-beam antennas that are reconfigurable and conformable to all platforms, thus enabling the evolving integrated land, air and space communications networks. The text begins with an up-to-date discussion of the engineering issues facing future wireless communications systems, followed by a detailed discussion of different beamforming networks for multi-beam antennas. Subsequent chapters address problems of 4G/5G antenna collocation, discuss differentially-fed antenna arrays, explore conformal transmit arrays for airborne platforms, and present latest results on fixed frequency beam scanning leaky wave antennas as well as various analogue beam synthesizing strategies. Based primarily on the authors’ extensive work in the field, including original research never before published, this important new volume: Reviews multi-beam feed networks, array decoupling and de-scattering methods Provides a systematic study on differentially fed antenna arrays that are resistant to interference caused by future multifunctional/multi-generation systems Features previously unpublished material on conformal transmit arrays based on Huygen’s metasufaces and reconfigurable leaky wave antennas Includes novel algorithms for synthesizing and optimizing thinned massive arrays, conformal arrays, frequency invariant arrays, and other future arrays Advanced Antenna Array Engineering for 6G and Beyond Wireless Communications is an invaluable resource for antenna engineers and researchers, as well as graduate and senior undergraduate students in the field.

Book excerpt: Two methods of synthesizing patterns from conical arrays were investigated during this period. In the first method the equivalence principle was used to synthesize patterns that are approximate duplicates of the patterns of representative planar arrays. This is done by evaluating on the surface of the cone the near field of a centrally located and mechanically steered hypothetical planar array. These near fields are used to calculate the required complex excitations of real elements on the surface of the cone to nearly duplicate the pattern of the hypothetical planar array. Patterns are presented of the results for two beam pointing directions. In the second method of synthesizing patterns from a conical surface, a heuristic approach was taken wherein the placement of the elements on the surface was based on extrapolations from linear and circular array theory and practice. Several element configurations are considered and numerous computer patterns are presented. The characteristics of these patterns are summarized by comparing in graphical form grating lobe levels, first sidelobe levels, and back-lobe levels for all of the patterns.
