directional coupler
Hi,
I want to use a Spectrum Analyzer to measure the return loss of an Antenna at certain frequencies. I've read that this can be achieved using directional couplers. Can anyone explain how the directional coupler will extract the reflected signal from the antenna, and what specifications are needed in the design of such a coupler (isolation, directivity, etc)?
Thanks in advance
