Abstract

The invention belongs to the technical field of wireless communication and antennas, and provides a novel low-profile dual-polarization base station antenna which structurally comprises a metal ring printed on the periphery of a dielectric substrate, a square-structure metal floor printed in the middle of the dielectric substrate, four square metal parasitic units printed on the front face of the dielectric substrate, two coaxial lines, a feed network connected with thecoaxial lines and a novel artificial magnetic conductor. Four square metal parasitic units in the antenna radiation structure are printed on the front surface of an upper dielectric substrate, a metal ring and a square metal floor are printed on the front surface of a lower dielectric substrate, a metal microstrip line connected with a coaxial line is printed on the back surface of the lower dielectric substrate, and a novel artificial magnetic conductor structure is loaded below an antenna radiation body. The antenna is low in height, large in resonance bandwidth, stable in gain, stable in half-power lobe width and high in isolation degree, and can be applied to a low-profile 2G/3G/4G base station antenna scene.

Description

technical field [0001] The invention belongs to the field of wireless communication and antenna technology, and relates to a novel low-profile dual-polarization base station antenna. Background technique [0002] With the advent of the 5G era, wireless communication technology has developed rapidly. At the same time, base stations have been widely used. Antenna is an important transceiver device of a base station, and the wireless communication system has stricter requirements on the performance of the base station antenna. For example, a base station antenna should have a sufficiently wide impedance bandwidth. With the rapid development of communication technology and the increase of communication frequency bands, the base station antenna should have a sufficiently wide impedance bandwidth to cover more communication frequency bands; secondly, the interference between different ports of the base station antenna should be small enough, therefore, the base station antenna s...
