Abstract
With the help of PCB strip line technology, insulators could decrease the phase velocity at odd mode and keep it unchanged at even mode. Based on this principle, we design and implement a broadband coupler, which is small, light, of low loss and good directivity, among many other advantages. The device can apply on POI, DAS, and microwave measurement systems. The band ranges from 727MHz to 2170MHz for variable applications.关键词
