Microwave horn antennas

Abstract

Microwave horn antennas are widely used as standard gain antennas for antenna testing or evaluation or feeds for other antennas due to their simple and solid geometries and excellent performances. Among many different types of horns, rectangular pyramidal horns and conical horns, multimode and corrugated horns are the most popular and practical configurations, and a selection of a specific type is made based on the design specifications such as bandwidth, gain and aperture efficiency, polarization, and some other unique radiation characteristics. With the advances in computational and optimization methods, more sophisticated designs such as profiled corrugated horns and matched horns are developed for demanding applications in radars, satellite communications, remote sensing, deep-space telemetry, and radio astronomy.
