The radar antenna—Circa 1995

This paper reviews some of the current interests in radar antennas, including work conducted at the U.S. Naval Research Laboratory. Almost all types of antennas have been used in radar, but it is the phased array which has received the most attention in recent years, especially for military applications. Methods for making phased arrays more affordable are discussed, as well as the potential of ferroelectric phased arrays, diode lens arrays (Radant antenna), agile plasma mirror, phased arrays employing fiber optics, and antennas for ultra-wideband radar. Also briefly mentioned are several areas where further radar antenna development might be indicated.
