A double-feed-point circular polarization microstrip antenna is characterized by sequentially comprising a metal patch, a dielectric substrate, a grounding plate, a pcb substrate and a mixed electric bridge feed unit from top to bottom, and all the components are integrated in a laminated and stickup mode; the metal patch and the grounding plate are arranged on the upper surface and the lower surface of the dielectric substrate respectively; the mixed electric bridge feed unit comprises a mixed electric bridge feed chip, feed probes, a grounding circuit and an isolated port circuit, and the mixed electric bridge feed chip, the feed probes, the grounding circuit and the isolated port circuit are all arranged on the lower surface of the pcb substrate; two output ports of the mixed electric bridge feed chip are connected with the two feed probes respectively, penetrate through the pcb substrate and the dielectric substrate and are connected with the metal patch on the upper surface of the dielectric substrate. Due to the positions where the two feed probes are located, while retaining phi=0 degree, a radiation waveform generates phase deviation of phi=90 degrees. Circular polarization radiation is achieved well, the bandwidth is large in the omnidirectional range, the antenna is small in size, low in section, light in weight and simple in structure, and the conformal effect is easy to achieve.
