Abstract
Bidirectional circularly polarized antenna element and bidirectional circularly polarized array antenna are provided, and comprising a dielectric substrate, a feeder, a radiation patch, a first plane, a second plane, a first coupling assembly and a second coupling assembly which are embedded in the surface of the dielectric substrate. The first plane and the second plane of the antenna element are kept at different heights, and compared with the solution that two planes at the same height can only generate linear polarization radiation in the prior art, the circular polarization radiation can be generated, which solves the problem of linear polarization mismatch. Furthermore, two coupling assemblies are introduced into two sides of the radiation patch to enable the coupling effect with the radiation patch, such that the frequency bandwidth of the circularly polarized antenna can be greatly improved without increasing the size of the antenna.
