Patent ID: 7864118

Claim:
A method of communicating a signal by a dual circularly polarized antenna system, said method comprising the steps of: providing a plurality of microstrip segments including a plurality of microstrip projections extending from each of said plurality of microstrip segments, wherein said microstrip segments are electrically connected forming subarrays; selecting a frequency; simultaneously receiving circularly polarized radiation from a plurality of directions from the plurality of microstrip projections; scanning said subarrays for a signal at said selected frequency; rotating said plurality of microstrip segments to enhance reception of said signal at said selected frequency; and receiving said signal at said selected frequency based upon the step of scanning said subarrays and the step of rotating said plurality of microstrip segments, wherein the step of providing the plurality of microstrip segments further include each microstrip segment in the plurality of microstrip segments being substantially straight and the plurality of microstrip projections comprising a plurality of pairs of microstrip projections, and each pair of microstrip projections in the plurality of pairs of microstrip projections connect at a point along each microstrip segment and extend out from the point of each microstrip segment.
