Problems solved by technology

[0004] However, facing the integrated metal slot array antenna, such as figure 1 As shown, it is composed of a feeder board and a feeder cable with integrated structure and function. According to the phase test principle, the unit to be tested is 1 / 2 of two adjacent complete ridges and the corresponding cable. At present, there is no corresponding phase The test device only indirectly guarantees the phase consistency of the antenna through the phase consistency of the feeder cable, but the size of each unit of the antenna feeder board will also affect the phase consistency, so the existing conditions cannot meet the requirements of the integrated metal slot Phase Test of Array Antenna

Abstract

The invention provides a phase test fixture for an integrated metal slot array antenna. On the platform, the first supporting board is set on the transmission device, the first supporting board is used to fix the array antenna, and the transmission device drives the units under test in the array antenna to align with the indicating antenna in turn for phase testing; the second supporting board is set on the On the installation platform, it can move longitudinally along the installation platform, and is used to fix the indicator antenna. The indicator antenna and the array antenna are on the same horizontal plane, and the distance between the unit under test and the indicator antenna test requirements is maintained; the absorber is arranged between the indicator antenna and the array antenna. Both sides of the test unit, covering the non-test part of the array antenna. The invention can improve the test confidence, meet the precise measurement of antennas of different sizes and specifications, and can realize the installation efficiency and testing efficiency of array antennas of the same kind and different sizes and specifications.

Description

technical field [0001] The invention relates to the field of phase testing, in particular to a phase testing jig for an integrated metal slot array antenna. Background technique [0002] Antenna is an essential device for wireless devices to transmit and receive radio signals. Its quality directly affects the performance of the device. It is of great significance to the test of antenna performance. With the continuous development of antenna products in the direction of arrays, each unit The requirements for phase consistency between antennas are getting higher and higher. The principle of antenna phase testing is mainly to perform phase testing by indicating the antenna and the antenna unit to be tested, wherein the phase difference between each antenna unit to be tested and the indicating antenna is kept within the required range. [0003] The traditional array antenna is formed by combining multiple unit antennas. Each unit antenna can be tested separately. The phase consi...
