| Zusammenfassung: | The utility model discloses a multi-beam switchable circularly polarized antenna, which comprises an antenna support frame and M same circularly polarized antenna units, and is characterized in that the antenna support frame comprises N surfaces, N is greater than or equal to 2, M is greater than or equal to 2, and N is greater than or equal to M; each circularly polarized antenna unit is respectively arranged on each surface of the antenna support frame; the circularly polarized antenna unit comprises an upper radiation patch oscillator, a lower radiation patch oscillator and an antenna circularly polarized feed power dividing plate which are sequentially fixed from top to bottom. According to the scheme, the structure is reasonable, the antenna performance is excellent, the scanning angle of the antenna to satellite communication can be greatly improved through alternate switching scanning of the M circularly polarized antenna units, and the requirement for the large elevation angleof satellite communicatio |
