wire transmissiion in Feko

Dear Friends,

I would like to make a simulation of traweling wave line (see figure-1)... the wire is excited using horn antennas...

I would like to excite and terminate a wire in Feko thru the freq range of 900MHz - 2GHz... I can excite the wire but I cannot terminate wire properly... So my S11 parameters thru the freq range are almost 1.12 dB... It means that I cannot terminate the wire properly.... How can I do it? if you could help me I will be really glad...

figure-1 traveling wave line

figure-2 wire excitation

figure-3 s11

with my best regards...

in this question, I would like to ask that how i can terminate a wire to avoid high reflection form the end of wire...

You could try adding a wire port and add a load to this port. You can also add a Spice circuit, which could be a matching network to the port.
