Hello Friends!
I am trying to simulate the structure in this paper: https://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=5765478&tag=1
A quick question, I have two monopole antennas (#1 and #2) and use the plane wave as the excitation. I want to sweep the excitation angle (0-360 deg with 1 deg step) to scan the plane wave. I am really confused how can I get the phase and magnitude information on the two monopole outputs? For example, phase1 and mag1 for monople #1, phase2 and mag2 for monopole #2.
The reason i want to use the plane wave excitation is I can easily sweep the scan angle in the simulation. But using plane wave, there is no S parameters on the monopole antennas' outputs (because the excitation is not a port anymore, S parameter is for port to port analysis). I tried many ways:
plane wave + two waveguide ports (on each monopole output) ;
plane wave + two voltage/current ports;
plane wave + two lumped ports.
I can not see the phase/magnitude information using these ways.
Up to now the only way works is that using far field horn/waveguide (with waveguide port excitation #3) as the source and put another two waveguide ports (#1 and #2) onto the monopole antenna bottom surfaces, so this time the S31, S32 can be obtained, which indeed include the phase and magnitude information. But using this way I have to rotate the horn manually each scan angle, so time-consuming....
I already searched this issue on the forum, this question has been ask several times, but no answer up to now. Anyone can give some clue on the simulation: scanning plane wave excitation to see the phase/magnitude information on antenna outputs? Many thanks!
