Abstract

The invention discloses an antenna testing system which comprises a signal transmission simulator, a channel simulator and a wave absorbing chamber, wherein at least two antennas are arranged in the wave absorbing chamber, the antennas are connected with the signal transmission simulator through the channel simulator and used for providing at least two paths of transmitting signals to equipment to be tested; the two antennas are positioned on a spherical surface taking the position of the equipment to be tested as the centre of sphere. Simultaneously, the invention also discloses an antenna testing method on the basis of the testing system. More than one testing channel model are arranged in the signal transmission simulator. A channel model is selected from the channel models, a wireless signal is transmitted according to the selected channel model and simulated by the channel simulator, and then the simulated wireless signal is transmitted through the antennas in the wave absorbing chamber; and the equipment to be tested which is arranged in the wave absorbing chamber receives the transmission signals of all the antennas, processes the signals and outputs the processing result. The antenna testing system and the testing method are easy to realize and have lower cost.

Description

technical field [0001] The invention relates to antenna testing technology, in particular to an antenna testing system and an antenna testing method based on the testing system. Background technique [0002] With the development of modern industry, all kinds of wireless communication products can only guarantee the quality of communication if they have good transmission and reception performance. The indicators to measure the transmission and reception performance include total radiated power (TRP, Total Radiated Power), total radiation sensitivity (TRS, Total Radiated Sensitivity) and space radio frequency performance (OTA, Over The Air), etc., among them, TRP must be higher than a set threshold to meet the corresponding communication requirements, and TRS must be lower than a set threshold, TRP and TRS are both satisfied When setting the threshold, the value of TOA means that the test index is good. [0003] In order to ensure the normal use of mobile terminal equipment i...
