I have designed a microstrip antenna in HFSS 9.0. initially I defined radiation boundary every plane without z=0 plane. I know that if I don't define radiation boundary, this plane becomes PEC. Than this design worked but resonance frequency shifted. Normally, I have resonance at 307 MHz, but in yhe simulasyon I have 284 MHz.
On the other hand, I extended air box and I define every plane of this box radiation boundary. Then I define bottom plane of the substrate and side of the coax as a PEC. But I didn't obtaine any similar results.
My question is how can I convert my initial design to second one. I want to define radiation boundary on the every plane. But I didn't achieve to work. Please help me.
I put my design here. Please look at it. if you inform me, I am very gratefull.
Sincerely,
