  I'm using HFSS circuit design and using my antenna created in HFSS as a component in the circuit. I have made the airbox around my antenna a radiation boundary. The size of the airbox is wavelength above and a wavelength below the antenna. But changing the size of the airbox changes the received voltage on my antenna, in the circuit design. What should be the size of the airbox for the results to be consistent and reliable?
