Multi-degree-of-freedom antenna test platform

Abstract

The invention relates to the field of antenna test devices, in particular to a multi-degree-of-freedom antenna test platform. The multi-degree-of-freedom antenna test platform comprises a horizontally-arranged movable mounting plate, the steering bearing sleeves are vertically arranged at the four corners of the lower end of the movable mounting plate correspondingly. Steering rotating shafts arevertically arranged in cooperation with the steering bearing sleeves. The steering rotating shafts downwards extend out of the steering bearing sleeves; steering wheel carriers are arranged at the lower ends of the steering rotating shafts; moving wheels are arranged at the lower ends of the steering wheel carriers through rotating shafts; a moving guide groove is horizontally formed in the middleposition of the moving mounting plate; a driving motor is horizontally arranged at the left end of the movable guide groove; by multi-angle movement, the multi-degree-of-freedom antenna test platformhas good maneuverability; the multi-degree-of-freedom antenna test platform is suitable for a high-strength testing environment, through a spatial multi-angle adjusting structure, the multi-degree-of-freedom antenna test platform can meet the requirement for fixed testing at any angle and any position within a certain spatial range, the testing performance of the multi-degree-of-freedom antenna test platform is remarkably improved, and through a multi-guide structure and coupling power supply, the operation stability and practicability of the multi-degree-of-freedom antenna test platform areremarkably improved.

Description

technical field [0001] The invention relates to the field of antenna testing devices, in particular to a multi-degree-of-freedom antenna testing platform. Background technique [0002] Antenna is an essential device for wireless devices to transmit and receive radio signals. Its quality directly affects the performance of wireless devices and has an important impact on the test of antenna performance. During the antenna test process, the polarization angle and pitch angle of the antenna need to be precisely positioned to test the ability of the antenna to receive radio signals in all directions in space. The most primitive antenna test is carried out manually, the measurement period is long and the error is large, so a special test system is required to test the performance of the antenna. Later, an electric turntable is used to adjust the polarization angle and pitch angle of the antenna. In order to ensure the phase center No change, usually the pitch motion needs to use ...

Problems solved by technology

The most primitive antenna test is carried out manually, the measurement period is long and the error is large, so a special test system is required to test the performance of the antenna. Later, an electric turntable is used to adjust the polarization angle and pitch angle of the antenna. In order to ensure the phase center No change, usually the pitch motion needs to use arc guide rail components, so that it can rotate 0-90 degrees

The equipment has the following disadvantages: first, the entire equipment is constructed of metal p
