Abstract:
1. A microstrip antenna adapted for use on a missile comprising: (a) first, second and third rectangular shaped 120-degree microstrip antenna elements mounted on an outer surface of said missile adjacent to one another, each of said first, second and third 120-degree microstrip antenna elements including: (b) said first, second and third 120-degree microstrip antenna elements generating a radiation pattern which includes horizontal polarization and vertical polarization with cross polarization at an operating frequency for said microstrip antenna of 231 MHz; and (c) said partial short circuit providing for a current flow pattern through said radiating element and said plurality vias to said ground plane for each of said first, second and third 120-degree microstrip antenna elements which allows for a substantial increase in the bandwidth of said microstrip antenna to ±400 KHz about the operating frequency for said microstrip antenna of 231 MHz.
