Hi everyone,
I am doing some simulations with the four patch antenna array. I used lumped port. The port is connected to the probe by transmission line. And the patch is fed by probe. I already did the matching work. However, when the length of the transmission line changes, the results of S parameters also change. Is it normal? Or I make a mistake somewhere? Can someone help me?
