Abstract

The invention provides a patch antenna with a reconfigurable directional diagram. The patch antenna comprises a microstrip resonator group, a first dielectric plate, a metal floor, a second dielectricplate and a switchable feed network which are sequentially stacked from top to bottom; and the antenna also comprises a radiation patch which works in a high-order mode TM02 and a TM20, wherein the radiation patch is placed above a microstrip resonator group in a suspended manner. The microstrip resonator group is composed of a first microstrip resonator and a second microstrip resonator which are orthogonal to each other; and the feed network is used for feeding the first microstrip resonator and / or the second microstrip resonator. The antenna has the advantages of low profile, light weight,enough bandwidth, simple structure, simplicity in operation, beam reconfiguration, stable radiation and the like; a communication system can realize reconstruction of three beams by controlling a feed conduction path of the feed network under the condition of not changing a hardware structure and a station layout; and the requirements of different application scenes can be met.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a patch antenna with a reconfigurable pattern. Background technique [0002] The antenna is the eyes and ears of the wireless communication system, and its performance determines the coverage effect of the system. In recent years, my country's mobile communication industry has developed vigorously, and 5G communication is gradually being commercialized. However, the frequency band of 5G communication is relatively high, the path loss is relatively large, and the coverage of macro base stations is very limited, which is prone to signal blind spots. The first challenge is undoubtedly the problem of signal coverage. In order to solve this problem, indoor distribution systems will be widely used, and micro base stations (pico base stations) will be arranged indoors and in areas with large data volumes. Due to the particularity of the application scenarios and the lar...
