Resonant cavity antennas

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

This article introduces resonant cavity antennas (RCAs) and leads the reader to develop an operational understanding of the design processes and considerations related to various types of RCAs. RCAs are a class of medium‐to‐high gain antennas, often having a single excitation location (as opposed to antenna arrays) and a simple configuration. These are a convenient alternative to antenna arrays and reflector antennas in space‐constrained applications where robustness, performance, and aesthetic appeal are equally important. The article discusses recent research results and trends particularly focusing on advances that have the potential to yield practical advantages, such as compactness, low profile, and high efficiency. The article reviews progress on gain bandwidth enhancement, achieving high aperture efficiency, multiband operation, and methods for aperture phase correction in RCAs.
