Phased array (PA) and reflector antennas are widely used in spacecraft, aircraft, and ground communications applications. This article provides design equations and guidelines that engineering professsionals can use for the quick and reasonably accurate design of these antennas without resorting to time-consuming simulations. It also provides insight into the various parameters and their impact on radio-frequency (RF) performance and antenna designs.
