Abstract
This invention belongs to a test device which particularly relates to a wireless transmission waveguide test device. The wireless transmission waveguide test device comprises a rectangle cabinet body. A cabinet cover is positioned on the cabinet body; two transmitters which are an upper transmitter and a lower transmitter are positioned on the cabinet cover; and a reception antenna is positioned on the side of the cabinet body opposite to the cabinet cover. The obvious beneficial effects of the invention are that the wireless transmission waveguide test device realizes working environment simulation for wireless transmission waveguide and the wireless transmission waveguide performs testing on signal transmission and wave absorbing performance of transmitters. The wireless transmission waveguide test device solves the dock that the absorbing reflectivity of the wave-absorbing cylinder material for a specific frequency electromagnetic wave can only be tested when the multiple layers of wave-absorbing materials haven't been rolled into cylinders. In most cases, the wireless transmission waveguide performance can only be verified through a large-scale experiment, but the wireless transmission waveguide test device can improve the working efficiency and save substantial experiment funds.
