Hi Xinglong,

We appreciate your patience on this query and thanks for reminding us to provide the response.

Please find the following suggestions/recommendations based on the details provided so far:

1. It is mentioned that the results of case 1 are changing with the size of the solution space. It looks like you are explicitly defining an air region and assigning a radiation boundary to it. Please note that it is recommended to have at least quarter of the wavelength distance between the radiating element and the boundary surface. You can use auto open region option available in the solution type window. Please check once.
2. Are you assigning perfect E boundary to the bottom of the air region? I do not see any sheet object defined in the model history tree. If that is the case, please create one sheet with the required dimensions and assign perfect E boundary condition (as the position of the box face will be changed as per point1).
3. It looks like the observation point falls under near-field region for the said frequency (200 MHz). Are you looking at the near-field calculations?

Kindly check the above points.

Best regards,
Praneeth.
