Abstract
An antenna system and a method for communicating signals by a dual circularly polarized antenna system are provided. The antenna system includes a substantially straight microstrip segment and a plurality of substantially straight microstrip projections. The plurality of microstrip projections extend from the microstrip segment in pairs at a predetermined angle, wherein each microstrip projection of the pair of microstrip projections extends from substantially the same location on the microstrip segment. A first microstrip projection extends from the microstrip segment on a first side of the microstrip segment and a second microstrip projection extends from the microstrip segment on a second side of the microstrip segment, such that the first and second microstrip projections at least one of emit and receive circularly polarized radiation in a first direction and circularly polarized radiation in a second direction simultaneously.
