Double-frequency broadband wall-mounted antenna

The invention relates to a double-frequency broadband wall-mounted antenna which comprises a reflecting plate, a low-frequency radiating element and a high-frequency radiating element, wherein the reflecting plate is provided with a feed network which feeds the low-frequency radiating element and the high-frequency radiating element; the feed network comprises a medium base plate, a low-frequencymatching network, a high-frequency matching network and diplexer, wherein the low-frequency matching network and high-frequency matching network are printed on the medium base plate by microstrip lines and respectively feed the low-frequency radiating element and the high-frequency radiating element and a diplexer is used for combining/shunting the low-frequency matching network and the high-frequency matching network; and the high-frequency radiating element comprises a half-wave symmetrical high-frequency oscillator, the low-frequency radiating element comprises a low-frequency oscillator, the high-frequency oscillator and the low-frequency oscillator are both realized in the form of the microstrip lines, an oscillator arm of the high-frequency oscillator presents a fan shape, and the low-frequency oscillator integrally presents an E shape. The antenna has the advantages of low profile, broad band, fine radiation performance index and the like.
