Hello,
I have set up an air box around my antenna and defined it as a radiation boundary. The box is distanced at a bit more than a quarter of the free space wavelength of the cenetr frequency from every side of the antenna (except the feeding side). The trouble is that when I increase the dimensions of the box, the antenna parameters (eg. S11) vary substantially.
Could anyoane please tell me how to choose the right dimensions for the box? Should I notice a convergence in the parameters around some box dimensions?
Thank you.
