Hi
I'm want to know how I should define ports
to my dipole antenna in Ansoft designer? THe antenna
is made on top of an substrate with only ONE metal
layer (signal layer), that means no ground layer.
How should I define my ports for this dipole
when I don't have an ground?
I have tried in
different ways but turned up in wrong simulations.
PLease give detailed help since the port options
are quite many
Does any one have an example,
project file demonstrating an simulation of an dipole
without groundplane?
BR

separate the dipole into two pieces of the same
length (so normally each one has got lambda/4),
the gap between them should be quite small. Now
you can use voltage gap source as a port (have a
look at the help "gap source").

In EM Planar Designer select Layout --> Layers
and define your substrate and dipole(Signal). After
select layer and draw a rectangle(your dipole).
Click Edit -->Select Edges and you must select
the end of rectangle.Click Draw -->Edge Port.
In the Project Manager you can see Excitations ,
Port1. Now you can Start Analysis Ps: I'm
sorry for my English!!!

Hello BR and others...
Did you ever successfully
implement your (electric?) dipole problem?
If so would you mind sharing some od the details
of your design.
I am trying to model a magnetic
dipole in free space (see topic"Ansoft Design User
Unite: Q on modeling a magnetic dipole" for more
details) and I could use any suggestions or help.
Thanks
Ebit

the (obvious) trick is to model the antenna
exactly the way you measure it. Needless to say
that you want to model the feedregion in your numerical
model just like the experimental model. I assume
you use a balun or an SMA endlauncher to feed the
dipole? I don't have any problems modeling dipoles
using HFSS
