Abstract

The invention discloses an array antenna apparatus. The apparatus is formed by a micro-strip antenna array, a baffle board and a phase shift feed network. The apparatus is characterized in that the micro-strip antenna array is formed by a plurality of antenna array elements according to symmetrical putting positions; for the antenna array elements, through four adjacent phase difference 90 degree feed ports, circular polarization performance of an antenna can be increased; and a phase shift feed network is located on the micro-strip antenna array and a back side of the baffle board and is formed by a medium circuit board and a plurality of phase shift power dividers. The size of the apparatus is small, consistency of the antenna array elements is good, good low elevation angle performance, good out-of-roundness performance and high isolation between the array elements are possessed, and the apparatus can satisfy adaptive anti-interference antenna application.

Description

technical field [0001] The invention belongs to the field of antennas, in particular to an array antenna device. Background technique [0002] The rapid development of modern technology has made antenna receiving equipment smaller and smaller, which is convenient for carrying and mobile testing. Due to complex factors such as terrain, environment, and weather, mobile workstations are easily affected by obstruction and environmental attenuation, and there may be high-power suppression interference signals during work. If the anti-interference ability of the antenna of the receiving device is not enough, the low elevation gain and the axial ratio performance are not good, in severe cases, the receiving device may not work normally, so the performance and anti-interference ability of the antenna of the satellite signal receiving device are more demanding. high. An important issue in the design of array antennas is the number and volume of antenna elements. It is required to h...
