Problems solved by technology

With the continuous increase of network coverage and capacity, more base stations need to be built, which will greatly increase resource consumption and base station investment costs. At the same time, the visual pollution of base station antennas is becoming more and more serious. In addition, due to the long The time is used outdoors, and the increase of base stations also makes the maintenance of the antenna more and more heavy

Abstract

The invention discloses a dual polarization broadband patch antenna which comprises a base, a first dielectric slab, a second dielectric slab and a metal cover plate, wherein the first dielectric slab and the second dielectric slab are arranged orthogonally. A ground circuit is attached to the base, printed circuits are carved on the first dielectric slab and the second dielectric slab, cable feed networks are attached to the printed circuits, the lower ends of the first dielectric slab and the second dielectric slab are fixed on the base, and the metal cover plate is fixed at the top ends of the first dielectric slab and the second dielectric slab. The +45-degree dielectric slab and the -45-degree dielectric slab are installed on the base in orthogonal mode. The dual polarization broadband patch antenna is operated under receiving and transmitting modes simultaneously through incoherence of electromagnetic wave vertical polarization and electromagnetic wave transmission multi-channel characteristics of a mobile communication system, saves antenna using magnitude of a single directional base station, reduces mechanical bearing of the base station, and is convenient to install, simultaneously saves antenna resources and base station investment, and enables the base station to be reasonable in layout and easy in site selection.

Description

technical field [0001] The invention relates to a dual-polarized broadband patch antenna, which belongs to the technical field of wireless communication antennas. Background technique [0002] The base station antenna is an important part of the mobile communication system, and its characteristics directly affect the overall performance of each wireless network. At present, most base stations use monopole antennas. With the issuance of 3G licenses in my country, the construction and operation of mobile communication networks of TD-SCDMA, WCDMA, and CDMA2000 standards have begun. The number of base stations required is huge, and the base station antennas Usage is also increasing. With the continuous increase of network coverage and capacity, more base stations need to be built, which will greatly increase resource consumption and base station investment costs. At the same time, the visual pollution of base station antennas is becoming more and more serious. In addition, due t...
