Experimental Study of Site-VSWR Method For Radiated Emission Test Sites Above 18 GHz

With the development of various wireless communication services such as 5G and Wi-Fi6E, the use of frequency bands above 6 GHz is increasing. For this reason, International Electrotechnical Commission (IEC) develops the measurement method of electromagnetic disturbance and test site validation above 18 GHz. This paper explores the site validation from 18 GHz to 40 GHz using the Site-VSWR method and evaluates the relation between SVSWR value and the transmitting antenna positions. From the results, the transmitting antenna position does not affect the S-VSWR value.
