As I understand antenna operate on frequency so one freqeuncy will be from what I am broadcasting and the other from where ever (but the same frequency) so I guess that would only be one input with one frequency of 2 different phases, I appologize for that. Then the phase shifter will always be working to ensure that the phases are 90 out of phase but I have to have a way to meause the difference in order to send the proper signal to the phase shifter.
Hmmm, what ? I'm afraid I'm not understanding your experimental setup. Nor do I understand what the purpose of your measurements is ? Perhaps a block diagram of the setup or some further description of what you're trying to do will help.
Antennae have both a frequency range (over which they work well) and a spatial range (over which they will transmit and/or receive w/o much loss). Are you transmitting a signal (of some sort) from 1 antenna to another and then trying to measure ... what, exactly ... ??? Where does the phase shifter (mentioned above) figure into this all ? Are you trying to create a PLL ?? If so, why ? Is the transmitted signal just an un-modulated carrier or ?? Are you trying to detect it's presence given that there's other interfering signals, or demodulate some information impressed onto it ??
I have a gut sense you're trying very hard to complicate something that, for an "RF person", is actually pretty simple. If you can describe what you're trying to do, instead of asking how to do it your way, you may get better answers.
