MIMO antenna design in HFSS

Hi, I have designed a four element MIMO patch antenna systems, and i have used SMA connector with wave port to excite the each antenna. Can anyone suggest me how can i terminate other waveports with 50 ohm impedence while other waveports are excited.

In HFSS, just use additional waveports. You select which ports to excite under HFSS->Fields->Edit Sources. The ones that are not excited will just absorb the mode. Furthermore, you can get all the relevant scattering parameters this way.

Yes, i did that, actually i did that but i got the same results for all ports. I am attaching you the base paper and HFSS file . can uoy please suggest to get the results given in the base paper.mimomultismamodify.rar04.15092104.pdf
