Abstract

The invention discloses a dual-polarized multi-system compatible antenna which comprises an upper-layer circular capacitance loading metal patch, a monopole metal column, an upper-layer medium baseplate, a first short-circuit pin, a second short-circuit pin, an annular metal patch, an intermediate-layer first medium baseplate, L-shaped probes, an intermediate-layer second medium baseplate, a metal floor, a bottom-layer medium baseplate and a bottom-layer Wilkinson power divider, wherein the Wilkinson power divider is connected with the two L-shaped probes which are orthogonal mutually for performing coupling feed on the annular metal patch, the outer edge of the annular metal patch is circular, the inner edge of the annular metal patch is elliptical, the ratio of a long shaft to a short shaft of an ellipse is regulated, and then the axial ratio performance of the antenna can be regulated; and the upper-layer circular capacitance loading metal patch, the monopole metal column, the first short-circuit pin and the second short-circuit pin constitute a capacitance and inductance loading monopole antenna by inductance loading, thereby effectively reducing the size of the antenna. The antenna has the characteristics of small size, large axial ratio bandwidth, large impedance bandwidth, compact structure and the like.

Description

technical field [0001] The invention relates to a multi-system compatible receiving antenna, in particular to a dual-polarization multi-system compatible receiving antenna which can be used for satellite navigation and wireless communication. Background technique [0002] With the development of wireless communication, the third-generation mobile communication 3G is favored by people for its high-speed data transmission and broadband multimedia services. It is gradually replacing the second-generation mobile communication to become the mainstream in the world today. The satellite navigation industry is a national strategic high-tech industry. It is a typical technology-intensive and service-oriented IT industry. Its development prospects are very broad. It is expected that in the next five to ten years, it will form a fusion of GPS, GLONASS, GALILEO and Beidou satellite navigation systems. A collection of global navigation satellite systems. [0003] With the development of...
