Zusammenfassung:A microstrip antenna for circularly polarized radiation including a substrate, a ground layer disposed on a first side of the substrate, a first radiating layer disposed on a second side of the substrate opposite the first side, one or more first electrically conductive pathways extending from the ground layer to the first radiating layer, wherein the one or more first electrically conductive pathways form a ring about an axis, one or more second electrically conductive pathways extending from the ground layer to the first radiating layer, wherein the one or more second electrically conductive pathways are disposed along a portion of a first line extending outwardly from the ring, and a feed conductor for connecting the antenna to a feed line.
