Problems solved by technology

[0005] For the method (1), the problem is that when using a base station antenna that supports multiple frequency bands in engineering, the common practice is to add a combiner at the signal input or output port of the base station antenna to realize the signal separation of different systems
However, this method is prone to severe signal cross-frequency interference and high installation error rate. The main limitation is that it cannot independently control signals that support different standards.
[0006] For (2), the problem is that when designing a base station antenna that supports multiple frequency bands,

Abstract

The invention provides a multi-system-supported multi-antenna array. The multi-antenna array comprises more than two radiating units of the same form, a reflecting plate, a feed network and a group of antenna input-output ports, wherein the radiating units and the feed network are positioned on two different surfaces of the reflecting plate respectively; the radiating units are electrically connected with each other by virtue of the feed network; the antenna input-output ports are connected with the feed network; radio frequency signals are received or transmitted by virtue of the group of antenna input-output ports. Input-output ports of high-frequency and low-frequency signals can be independently controlled, bipolar signal coverage of +/-45 degrees is performed, and the multi-antenna array is simple in structure and low in cost.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a multi-system multi-antenna array, and the invention can be widely used in the field of mobile communication base station antennas. Background technique [0002] The development of the mobile communication industry has gone through the process from 2G to 3G, and from 3G to 4G. The needs of users have gradually shifted from voice calls to data services, and from data services to high-speed data services. In this process, 2G, 3G and 4G will coexist for a long time. For mobile communication base station antennas, the existence of a multi-standard system requires the antenna to support multi-band work. At present, there are two main design methods for base station antennas that support multi-band operation: [0003] (1) Design a broadband or ultra-wideband radiating unit and a feed network to support multi-band work at the same time; [0004] (2) Design a variet...
