two element antenna array

Hi ,

Plz I need your help

I design single element patch antenna and want to do two element how can i do that ? using IE3D

and How can i feed by Coaxial ?

I know how to feed by feedline .

Thanks alot

and i really wait your reply plz take care

:) if you use CST Microwave studio I'll help u

First of all, u need to know that IE3D cannot simulate an exact coaxial feeding like what we do in HFSS. The practical way to emulate an coaxial excitation is to use the vertical localized port. There are plenty of examples of such feeding in IE3D manual.
