Design of the Near-field Coupling Test Antenna Based on Planar Helical Structure
With the rapid development of 5G NR and WiFi6E/7 technology,it is also a big challenge for the fields of wireless communication testing.At present,MIMO technology has been widely used in various products in our life,the high integration of chips and the related development of array antennas would make many products have no corre-sponding RF ports in the future.The use of traditional conducted methods for RF parameters and throughput testing will inevitably not meet the test requirements of such products,so the design of an ultra-wideband circularly polarized near-field test antenna suitable for different test scenarios is an important problem for us to solve.
