Re: VERY GOOD COLLECTION OF HFSS 10 PROJECTS

hi ...
this file may helpful for you

does anyone have a patch example for download?

Check out this one:

In this link there is a tutorial for easy simulation of microstrip antennas.

hi all,
i am working on a rectangular spiral microstrip antenna. i am using coaxial feed, but the problem is, i am getting radiation in exactly opposite direction. i working with HFSS 10. Please help.

can you post a picture if your hfss design? because i think your feeding technique is wrong. and did you try applying a ground plane in your whole antenna, this would reflect the whole radiation in the direction opposite to it.
For this, insert a surface and just declare it infinite ground plane from the boundaries.

this is how it looks, i have applied ground but finite one. infinite ground is impractical. i have to fabricate this antenna.

also this is the radiation pattern of above design..

and yes i did get radiation pattern above patch when i inserted infinite ground.
can you help me to get correct pattern without infinite ground?

Any Help on this.. ? am a Total Newbie about all this..

plz i want a butler matrix design with HFSS
