How to fed this antenna in HFSS?

i have seen such antenna.you need to fed it from the center point. even you can structure a SMA connector at the center of antenna & fed via.

hellow, using CST mws to simulate this kind of antenna is much more convenience. you can use discrete port.

Easy, like the guy above said use an SMA feed. With HFSS its easy but will take an hour or two. If you use EMCoS, its gonna take not more than 10 minutes.

mhmm ... and how to feed this antenna in 'real life'

- connect the hot end to the center of the antenna!
- where to connect the cold side?
