Ultra broad slant polarized omni azimuthal antenna

A slant polarized omni azimuthal antenna covering 2 to 26 GHz (13:1 frequency bandwidth) has been designed and developed using only three layers of printed circuit polarizers. The design approach and performance optimization of the antenna are discussed. The antenna has an omni variation of /spl plusmn/ 3 dB and a nominal gain of 0 dB over the frequency band. It is lightweight, compact, and ideally suited to surveillance applications. A low-loss, lightweight radome is also developed to protect the antenna from hostile environments.<<ETX>>
