Detection of Return Loss in Microwave Anechoic Chamber

Return loss is one of the important indices, which is used to evaluate the absorbing characteristic of the microwave anechoic chamber, so the test of it comes into one of the important aspects of examining the characteristic of th e microwave anechoic chamber. This paper presents the theory basis and a set of scheme for measuring return loss in microwave anechoic chamber by the scalar net work analyzer. The method advised in this paper is surely to be a good solution to evaluate the characteristic of the microwave anechoic chamber as it's simple, practical and clear. In the end, a practical example of measuring our microwave anechoic chamber is given.
