Hello guys,
I am using CST.I am implementing Full Duplex wireless communication using Antenna Cancellation Technique, where i am using two transmitters at a distance of d and d+lambda/2 from the receiver to nullify the self interference(see the diagram).
For this i am using two transmitters and one receiver(I am using monopole).To make this i am exciting only ports 2 and 3 which I am considering as transmitters(see the diagram).
I am facing the problem that i am not receiving any change in my s12 n s13 parameters when i am exciting port 2 n port 3 simultaneously; from the one in which i am exciting only port 1 or only port 2.
ie.s12 when only port 2 is excited should be different from the s12 that i am getting from simultaneous excitation of port 2 n 3(coz it wud inculcate the effect of port 3 as well).
Either i am not exciting my Tx antennas correctly or the S parameter results are not getting combined correctly.
Kindly help me to get my results.Any help wud be highly appreciated.Thanks in advance.
