This is my models, a pec cavity, an antenna, a load in the cavity. The cavity is just a shell, empty inside. Energy is fed into the antenna through coaxial port. I want to check the S11 parameter.
My center frequency is 2.45GHz. The length, width, and height of the cavity are 470mm, 470mm, 270mm. Background set to Normal, Boundaries set to open.
I found it takes a long time to simulate. I have tried time domain, frequency domain, eigenmode... . And it seems that the simulate didn't converge. How should I set the Solver?
Really needs help!
