Abstract

A linear polarized patch antenna structure receives circular polarized signals and offsets polarization loss to improve receiving signals quality. The structure includes a body made of ceramic, a main plate is set on an upper end surface of the body, a ground plate is set on a lower end surface of the body and is insulated from the main plate, and a signal transmitting terminal goes through the body and electronically connects with the main plate. Thus, elements are miniaturized and electric demands of signals received by the antenna are satisfied.
