Abstract

We describe an antenna that will operate over the band from about 1225 MHz to 1630 MHz and thus cover both GPS and Iridium frequencies. This antenna radiates nominal right hand circular polarization at elevation angles above about 5/spl deg/ and was designed with a process that uses a genetic algorithm (GA) in conjunction with an electromagnetic code. In this method the beamwidth, VSWR and frequency band are specified and the antenna configuration that most closely produces these characteristics is synthesized.
