Abstract

The invention provides an array antenna synchronous rotation platform, an array antenna and a use method of the array antenna synchronous rotation platform, and aims to solve the problem of synchronous rotation of an antenna array. The synchronous rotating platform comprises a plurality of circular rails with the same central axis, rail flat cars are evenly distributed on the circular rails in the circumferential direction, a supporting shaft is arranged on the central axis of each circular rail, a center platform is rotationally arranged on the supporting shaft, and the rail flat cars are connected with the center platform through truss arms. The center platform is driven by the rail flat car to rotate, overlarge bending stress of the truss arm caused by center driving is avoided, gear transmission is avoided, and gear contact fatigue accidents are avoided; and the directions of the antennas arranged on the rail flatcar are kept consistent, so that the working state of the antenna array is kept unchanged.

Description

technical field [0001] The invention relates to the technical field of array antennas, in particular to an array antenna synchronously rotating platform, an array antenna and a method for using the same. Background technique [0002] The short-wave antenna has the advantages of long propagation distance and small loss. In order to enhance the beam width of the short-wave antenna, a common method is to form an array of multiple sets of antennas according to the set layout to achieve phase control and increase the actual demand for gain. The logarithmic periodic antenna is a kind of short-wave antenna, and the logarithmic periodic antenna is a directional antenna with extremely high directional gain. When using this antenna for array formation, it generally needs to have a 360° rotation to point to the communication direction. And it is necessary to keep the overall shape and direction of all antennas in the array unchanged. [0003] For logarithmic periodic antennas, it is g...
