The invention discloses a feed structure, an antenna unit and a multi-array antenna. The feed structure comprises supporting sheets and feed baluns; the maximum height of each supporting sheet is 16-19mm in the vertical direction; the feed balun is attached to the surface of the corresponding supporting sheet in the vertical direction; and each feed balun comprises a positive electrode balun and a grounding balun. By means of thinning the positive electrode balun and thickening the grounding balun, the optimized antenna performance can be obtained, and the compact antenna structure and the large-scale antenna are formed.
Description
technical field [0001] The invention mainly relates to the field of wireless communication, in particular to a feeding structure, an antenna unit and a multi-array antenna. Background technique [0002] With the rapid development of economy and urban construction, high-rise buildings are becoming more and more dense, the height of buildings is also increasing, and users are dense. Wireless communication in high-rise buildings has problems such as signal coverage, signal strength, and communication capacity, and has higher requirements for the number, capacity, and radiation performance of building coverage antennas. The existing antenna structure cannot meet the height requirement, the cost is high, the structure is complex and bulky, and the radiation performance is insufficient. Contents of the invention [0003] The main purpose of the present invention is to provide a feeding structure to solve the problems of insufficient radiation height, complex structure, large si...
