Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to an improvement of an antenna component or a device combined with an antenna. Background technique [0002] Circularly polarized antennas can receive incoming waves of various polarizations, and their circularly polarized radiated waves can also be received by antennas with arbitrary polarization. Therefore, circularly polarized antennas have been widely used as antennas for aircraft and mobile devices [1 ]. Among them, the circularly polarized microstrip antenna is widely used in the fields of wireless communication and satellite communication because of its small size, light weight, and low cost. Although circularly polarized microstrip antennas are widely used, circularly polarized microstrip antennas also have shortcomings such as narrow frequency band and small power capacity, which limit their application scope to a certain extent.
