Description

technical field [0001] The invention relates to an electromagnetic wave detection system, in particular to an electromagnetic wave detection system arranged in an anechoic chamber. Background technique [0002] In modern society, electronic products are almost ubiquitous. Every electronic product will generate more or less electromagnetic waves when used. Excessive electromagnetic wave intensity will cause harm to the human body. Electronic products must go through electromagnetic wave inspection and testing before they are listed or exported, and only products that pass the inspection can be approved for listing or export. [0003] The current way to test electromagnetic waves is to place electronic products in an anechoic chamber for testing. See Figure 1A , Figure 1B , Figure 1C and Figure 1D , which are respectively the first schematic diagram of the traditional radio wave detection system, the second schematic diagram of the traditi...
