Hfss design file for slot antenna needed

Can anyone upload a working simple microstrip-fed slot antenna design file in HFSS. I have been trying to simulate one for months, but I only get an unacceptable radiation efficiency of more than 1.0 and and unrealistic gain of 5dB. Please help me!


PS: 2.4Ghz antenna, if possible.

here attached. You should optimize the project in this file as did it quick (generated with ADK). The radiation efficiency here is 98.4%.
5 dB gain is not bad.

Hi olule,
You can use Antenna Design Kit with HFSS to get your design. (Need not to draw the slot antenna, Design kit will draw for you).
