Hey, I am designing a rectangular patch antenna and I am facing an issue that I don't know what should I do. I am trying to design an antenaa that will resonate inside of water box with some other substances that has dielectric constant of er=33. But I don't know how big the box must be and also why by changing the dimensions of the air box (radiation box) the results are also changing (the radiation box is always larger than λ/4 starting for the edges of the water box)?
The designers of HFSS Ansys say that this must not happen and that the dimensions of the radiation box must not affect the results (on condition that the dimensions are larger than λ/4).
Thank you in advance.
