The cost of low-frequency microwave anechoic chamber is lower than that of rectangular one, but the cross polarization and path loss of conical one depend on its section symmetry. Problems in application: A practical microwave darkroom needs not only good electrical performance design, but also relevant technology 1. Auxiliary rooms are supporting test rooms and indoor life, with complete working facilities. 2. The door and observation window of the microwave darkroom. The design and construction of the microwave darkroom door will directly affect its electrical performance. In particular, the leakage of electromagnetic wave from the screen door of the microwave darkroom should not be lower than a certain value. It should not be placed in the main irradiation area like the absorption door. The observation window hole is used to observe the working conditions in the room. Now some have adopted the television monitoring system. 3. The microwave dark room is provided with a turntable, a bracket and a matched guide rail for moving the measured body. It is required to be easy to use and have small reflection to electromagnetic wave. 4. The lighting and illumination in the microwave darkroom is very necessary. It can be realized in many forms. Pay attention to the distance between cooling and absorbing materials to prevent fire. It is better to use cold light source. Technical parameters:
