Mode-Inspired Wideband and Multiband Planar Antennas delivers a complete engineering methodology for designing wideband and multiband planar antennas with a focus on mode-inspired theory. Understand the evolution of planar antenna technologies and the critical bandwidth types, including Impedance, Isolation, Gain, and Pattern. This book offers the practical and theoretical foundations of characteristic and cavity mode analysis to enable the production of low-profile, single-layer planar antennas that are both compact and high-performance.
Dive deep into the exact methodologies and techniques that form the theoretical basis for bandwidth control across all domains. Gain detailed knowledge of essential strategies like harmonic suppression, even/odd mode control, and coupling interface design for improving port isolation in MIMO and full-duplex systems. Also cover the implementation of high and stable gain approaches for directional and GPS-based systems, as well as advanced radiation control for half-power beamwidth (HPBW), reducing sidelobes and cross-polarization, and designing scanning-beam strategies. Further consideration is given to applications for biomedical and implantable systems in space-constrained or high-demand environments.
This resource is an essential tool for RF engineers, antenna designers, academic researchers, graduate students, and wireless communications professionals working with advanced planar antennas. Get solutions to key problems such as achieving high-performance in compact and low-profile designs, improving port isolation in MIMO systems, and optimizing gain and radiation patterns for a variety of challenging applications, from mobile antennas to conformal antennas and GPS systems.
