Abstract

A cross polarization antenna comprises a substrate, a first impedance converter, a second impedance converter, a first cross polarization antenna and a second cross polarization antenna, wherein the first opening of the first cross polarization antenna is corresponding to the second opening of the second cross polarization antenna, and can be spatially arranged crosswise without contacting with each other. The cross polarization antenna can effectively receive electromagnetic waves from various polarization directions to reduce polarization loss, and is fabricated integrally to achieve convenient fabrication and assembly and low fabrication cost.

Description

technical field [0001] The invention relates to an antenna, in particular to a cross-polarized antenna which is formed by intersecting two integrally formed antennas. Background technique [0002] The radio frequency signal output by the radio transmitter is transmitted to the antenna through the feed line, and the antenna radiates to the outside world in the form of electromagnetic waves. When the electromagnetic wave is transmitted to the receiving point, the electromagnetic wave is received by the antenna, and then the radio frequency signal is transmitted to the radio receiver through the feed-in line. [0003] Generally speaking, the antenna radiates electromagnetic waves to the surroundings, and the electromagnetic waves are composed of an electric field and a magnetic field, wherein the direction of the electric field is the polarization direction of the antenna. Therefore, the electromagnetic waves that antennas with different polarization characteristics can receiv...
