Small-sized linear polarization receiving and transmitting integrated same-frequency antenna

The invention provides a small-sized linear polarization receiving and transmitting integrated same-frequency antenna. The antenna comprises at least one antenna body, each antenna body comprises a substrate, a first radiation body and a second radiation body arranged at the first surface of the substrate, and a feed circuit arranged at the second surface of the substrate, wherein the first surface is far away from the second surface, the first radiation body and the second radiation body are symmetrically arranged about the diameter of the at least one antenna body, the feed port of the firstradiation body and the feed port of the second radiation body are connected with the feed circuit through a feed line, and the first radiation body and the second radiation body are in G-like shape by connecting a plurality of sections of resonance pieces in order and form a plurality of resonant frequencies. According to the technical scheme of the invention, the small-sized linear polarizationreceiving and transmitting
