Abstract
A compact broadband circularly polarized antenna includes an antenna body, wherein a cavity is formed in the antenna body, a plurality of ridges and a plurality of baffles are formed inside the cavity, the ridges are configured for antenna miniaturization and bandwidth widening, and the baffles are configured to form a spatial phase difference. In the present disclosure, the ridges of the circularly polarized antenna are divided into two parts, wherein the ridges located in a baffle mounting rectangular section and a front rectangular mounting section are configured for antenna miniaturization and bandwidth widening, and the baffles for forming a phase difference are arranged between the ridges located in the baffle mounting rectangular section. Through the above arrangement, the polarized antenna may be miniaturized, operate in a millimeter wave band, and achieve circular polarization; the bandwidth of the antenna is relatively wide.
