Background
The 5G communication system is more and more commercialized, and unlike the previous 2G, 3G and 4G, the 5G communication system uses a frequency band above 10GHz for information transmission, and this frequency band is generally referred to as a millimeter wave frequency band in the industry. Since the frequency difference between the millimeter wave frequency bands (28GHz, 39GHz, and 73GHz) and the previous communication frequency bands (700MHz to 3GHz) is very large, the SAR (specific absorption rate) which was originally an evaluation unit for electromagnetic radiation of communication devices is no longer suitable. For electromagnetic radiation in the millimeter wave band, Power Density (Power Density) is used as an evaluation unit. Due to the change of the evaluation scheme, the traditional typical SAR test system (the probe is inserted into a model filled with tissue simulation liquid, and the tested communication equipment is placed below a model shell) for electromagnetic radiation of 2G, 3G and 4G communication systems is not suitable for testing millimeter wave frequency bands in 5G.
According to international standards, for testing the electromagnetic radiation of wireless communication equipment, all surfaces (for example, a cuboid is 6 surfaces including front, back, left, right, upper and lower surfaces) of the equipment to be tested need to be tested, and the maximum value of the electromagnetic radiation is determined. Due to the structure and physical characteristics of the existing 5G millimeter wave system, the existing 5G millimeter wave test system can only measure the upper electric field of the tested 5G communication equipment, and the existing 5G millimeter wave test system can only be horizontally placed on a test board for front and back tests because no proper support is used for supporting the tested 5G communication equipment, so that the power density test can not be carried out on all test surfaces of the 5G communication equipment according to the international standard.
