Hi,
I would like to know how to design an antenna with particular polarization..
For example some one ask me to design "A wide band Antenna with circular polarization.. "?
How will we decide it in HFSS..? |

Wideband antenna with circular polarization is not easy.
You should start with an antenna that is designed for circular polarization already - like a helix antenna or a spiral. Patch antennas can have circular polarization over a very small bandwidth, but you won't get wideband.
You have no chance of coming up with a new wideband circular polarized antenna off hte top of your head.
So choose one that works at optimize it for your specific band and application. |

When somebody asked to design an antenna , we give several specifications like BW,gain,Polarization etc...
Then how to design an antenna with desired polarization?  |
