A dual circularly polarized antenna system and a method of communicating signals

摘要

An antenna system (30) and a method (100) for communicating signals by a dual circularly polarized antenna system (30) are provided. The antenna system (30) includes a substantially straight microstrip segment (32) and a plurality of substantially straight microstrip projections. The plurality of microstrip projections extend from the microstrip segment (32) 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 (32). A first microstrip projection (36A) extends from the microstrip segment (32) on a first side of the microstrip segment (32) and a second microstrip projection (36B) extends from the microstrip segment (32) on a second side of the microstrip segment (32), such that the first and second microstrip projections (36A,36B) emit or receive circularly polarized radiation in a first direction and circularly polarized radiation in a second direction simultaneously.
