Abstract

The invention discloses a full-band navigation antenna, which includes an antenna top loading A, an antenna top loading B, a floor, four antenna elements A, four antenna elements B, four outer antenna parasitic arms, four inner antenna parasitic arms and four feed elements ;Each feed element includes an outer arm and an inner arm, and the four feed elements are evenly distributed on the floor; the inner arm and the outer arm of the feed element generate a resonance point, and a dual-frequency signal is generated through the outer antenna parasitic arm and the inner antenna parasitic arm Effect, thereby widening the bandwidth, realizing circular polarization through the four-power split coupler of the motherboard circuit. The present invention is simple in structure, reasonable in design, has the advantages of low material cost, wide frequency band, uniform gain of each frequency point, etc., does not need special high-frequency materials, and only needs ordinary FPC to be pasted on the plastic surface to basically realize all the above functions. The low-elevation gain of the antenna is also relatively high, and the signal is still good for weak signal areas.

Description

technical field [0001] The invention relates to a satellite antenna, in particular to a full frequency band navigation antenna. Background technique [0002] The Beidou satellite navigation system is a global satellite positioning and communication system independently developed by my country. Together with the US GPS, Russia's GLONASS, and the EU's Galileo system, it is known as the world's four major satellite navigation systems. At present, the United Nations has confirmed these four systems together as the core suppliers of the global satellite navigation system. It has changed the long-term lack of high-precision and real-time positioning means in my country, broken the monopoly position of the United States and Russia in this field, and can provide a variety of business guarantees for various military and civilian uses of land, sea, air and space in my country. In particular, it is of great significance to improve the modernization of national defense in our country. ...
