The invention discloses a microstrip antenna to solve the technical problem in the prior art that the bandwidth of an existing circular polarization microstrip antenna is relatively narrow. The microstrip antenna comprises a radiation patch used to radiate electromagnetic waves; a dielectric plate with a first surface and a second surface arranged in opposite wherein the radiation patch is arranged on the first surface; and at least one metal sheet arranged on the second surface at a position opposite to the radiation patch. The at least one metal sheet and the radiation patch form at least one capacitor; and the at least one capacitor is used to compensate the inductive reactance of the microstrip antenna. 本发明公开了种微带天线，用于解决现有技术中圆极化微带天线的带宽较窄的技术问题。该微带天线包括辐射贴片，用于辐射电磁波；第介质板，包括相对的第表面和第二表面；其中，所述辐射贴片设置于所述第表面；至少个金属片，设置于所述第二表面，且位于与所述辐射贴片相对的位置；所述至少个金属片与所述辐射贴片形成至少个电容，所述至少个电容用于补偿所述微带天线的感抗。
