How to terminate a waveguide port with a matched load in CST?

Hi,

I have a T-splitter with the attached configuration. It has quarter wave matching section to match the narrower feedlines to the 50ohm line.

My problem is how to terminate the antenna at Port 2 & Port 3 with a load impedance of 50Ω?

Cheers!

Use a branch line coupler instead of your T-splitter.
