| Zusammenfassung: | The utility model relates to antennas and discloses a traveling-wave type multi-beam circular polarized antenna, which comprises an antenna and a feed network (4). The antenna includes a PCB printed circuit board (1), and the PCB printed circuit board (1) comprises an upper metal surface (11), a lower metal surface (12) and a medium substrate (2) arranged between the upper metal surface (11) and the lower metal surface (12). The traveling-wave type multi-beam circular polarized antenna adopts a substrate integrated waveguide structure and the technology of circular polarization and space time spreading, reserves high gain and high radiation efficiency of waveguide slot, overcomes multipath effect and effectively uses frequency spectrum resources. |
