 25 Aug 2008 10:54 HFSS-antenna parameters question |
|
|
|
Dear All,
I have tried to simulate a printed antenna. When I read antenna parameters, I got Directivity < 1, gain is very small and a very small radiation efficiency, which indicates an error in simulation. Then I have set the radiation box mesh to about lambda/10, I got reasonable directivity, but the values of gain and efficiency are still too low. Anyone can help? Thanks.
Best Regards,
Mshafee

Dear amu811,
Thanks for your reply. The radiation box is lager than lambda/4, but I still get unacceptable gain and efficiency.
Best Regardsd,
