Declaring the radiation boundaries for a radiating structure in HFSS

hi everyone,

can anyone please tell me exactly what goes in to declaring the radiation boundaries for a radiating structure and how does it affect the accuracy of results obtained?

The radiation boundaries, it is recommended, to have quarter wavelenght from the radiating structure, if you want to obtain farfield solution results. For the radiation boundaries box manually meshing should be performed on to get accurate results for properties such as efficiency, directivity, and radiation pattern (if you model a antenna). One should seed lambda/10 for the radiation boundaries box. More detail http://www.emtalk.com/tut_1.htm

thanks alex,

i'll try a few things and get back to you with any more doubts i may have..
