Abstract

The invention discloses a broadband low-profile antenna with a reconfigurable directional diagram. The broadband low-profile antenna comprises four antenna units which are distributed in a two-dimensional array in vertical and horizontal directions, four switches in one-to-one correspondence to the antenna units, and a one-into-four equal-amplitude equal-phase power distributor, wherein each antenna unit is provided with two feed ports; the feed ports of each antenna unit are connected with the switches through a corresponding microstrip transmission line (7); four branches of the one-into-four equal-amplitude equal-phase power distributor are connected with the switches respectively; and the switches are used for controlling the equal-amplitude equal-phase power distributor to be fed to one of the two ports of each antenna unit separately for realizing that only one of the two ports of each antenna unit is in the working state. The broadband low-profile antenna has the advantages of low profile, broad band, simple structure, easy integration, as well as consistency, easy realization, low cost and the like.

Description

technical field [0001] The invention relates to a reconfigurable antenna with a broadband low-profile pattern and belongs to the technical field of antennas. Background technique [0002] The rapid development of wireless communication technology has put forward higher requirements for system requirements and working modes. The traditional single-function antenna cannot meet the current needs well, and has become a bottleneck restricting the development of system performance. The proposal and development of reconfigurable antennas provide a good solution to these problems. The pattern reconfigurable antenna can control the main beam and null direction of the antenna according to actual needs and environmental changes. At the same time, with the rapid growth of communication services, the system has higher and higher requirements on the available bandwidth of the antenna. [0003] Since the modern single-layer PCB technology is very mature, the processing accuracy is also g...
