Dual-polarized antenna structure, antenna housing and designing method thereof

Abstract

The invention discloses a dual-polarized antenna structure, an antenna housing and a designing method thereof. The dual-polarized antenna housing comprises multiple layers of medium substrates, wherein a plurality of metal patterns arranged in an array mode are arranged on the surface of each medium substrate, and are not changed in the patterns which are rotated at 90 degrees around the axle center vertical to the medium substrate.

Description

technical field [0001] The invention relates to a dual-polarization antenna structure, a radome and a design method thereof, in particular to an antenna which can increase the gain of the antenna. Background technique [0002] The essential component of the wireless communication system is the front-end circuit antenna, whose characteristics are related to the signal quality of the entire system. In general, the received signal strength is determined by the following formula: [0003] P R = P t × e t e r × D t D r × λ 2 ( 4 πr ) [0004] Among them, P R is the receiving power at the receiving end, P t is the transmit power of the transmitter...

AI Technical Summary

Problems solved by technology

However, the above-mentioned technologies will encounter the following disadvantages in practical application: 1. The signal loss of the feeding network is greatly increased; 2. The design of the feeding network is complicated; 3. The overall volume of the antenna becomes larger; The antenna gain cannot be effectively increased, the maintenance of base station lines is difficult and expensive, and the designed antenna is not suitable for application on small base stations due to its large size

The height of the radome of the Fabry Perot structure needs to be about 0.25 to 0.5 times the wavelength, so that the antenna size cannot be effectively reduced due to the large size of the antenna; and the metal total reflection surface is a necessary component, which limits its application
