With the development of antenna technology, antenna test technology is also developing. As far as the antenna pattern test method is concerned, it is well known that the method is outdoor far-field test. However, due to the rapid development of microwave absorbing material technology and computer, as well as the maturity of other disciplines, such as holography technology, the pattern testing technology has developed from outdoor field testing to a variety of testing methods that compete with each other and complement each other. From the previous outdoor test to indoor test, outdoor test is the auxiliary. In recent years, a large number of microwave darkrooms have been built and used, which is a distinctive sign. The main function of the house is to install the absorbing materials, so that the inner wall, ceiling and floor of the room reflect little to the received electromagnetic wave, so as to better simulate the free space environment and test the indoor antenna.
