Hello,

I am new to Ansoft HFSS. I am designing an omni-directional antenna for [2-18Ghz] Band. I have designed ungrounded CPW partial circular patch antenna USING HFSS V 13.0 and are facing the following difficulties:-

1. how to choose the solution frequency for the required band. What should be the solution frequency of my antenna
2. WAVEPORT: What should be the dimensions of the Waveport & how can I get the field lines which should be good inward as described in hfss book………..
3. VSWR: what parameters should I change to get a good VSWR AND good Return loss


I shall be very thankful to you people if you help me out of these problems kindly help me………..

me too, so I am not going to offer you any advice on using it.

If the VSWR is good, then the return loss will be good. Conversely, if the return loss is good, the VSWR will be good. There is a simple mathematical relationship between the two.

i have succesfully designed my antenna but now i want to find out whether it is horizontal, vertical or circular polarized......... can you tell me how to check it
 

it dont have circular polarization
and about vertical and horizontal u can check by polarization in phi and theta
 

hi sir ferdows, i have designed uwb antenns exactly as in papers but return loss is very bad,plz make corrections in uploaded file as soon as possible
