Hi, I would like to import a pattern diagram in cst and to generate a array antenna with it. Is it possible?
Thank you in advance

In my opinion, the Negative step (step 2) is really not necessary. If the solids you draw are all PEC, just import them into cst, set the background material to be free space, set the objects imported to be PEC. Then cst is "smart" enough to know that the fields needs to be solved are in your "Negative" region. Similar thing happens when using HFSS

I'm designing a small circular loop antenna (single turn) in cst MWS.I'm just very confused about the radiation pattern i'm getting. I've been reading in textbooks that the radiation pattern of the loop antenna is like a dipole and must be in the plane of the antenna, i.e. the direction of the max radiation is NOT through the loop.

To desigh the patch antenna You can use 2.5D simulator (MWO, Sonnet), or cst-MWS if Your structure has many layers. To Yagi-Uda ... usually the formulas from Balanis book gives the good result, but if You want to simulate it, try to use SuperNEC or cst-MWS.

1.5G? It must be quite a big structure! 8O What were your mesh settings? I noticed that cst uses a lot more mesh cells if you haven´t got a planar structure (such as a curved body of an aircraft) I had to use staircase mesh for the imported sheet body. Till now, I still haven´t got the hang of disabling automatic mesh

there is low backlobe but if you have two sidelobs obviously they are marked with the green line

You should consult the cst MWS documentation on "Vertical and Horizontal Polarization". It is explained well in that section.

I've got a problem when using a discrete port in cst Microwave Studio 5.1.2. It's a pretty basic thing, I think.
I want to do a transient analyses for a simple monopole structure. So I choose a discrete port between the monopole and the PEC surface. In the manual they state that such a discrete S-port has to be small enough, at least 1/1

cst calculates the gain as the total received power so it includes both Ex^2 + Ey^2. if you need the gain of horizontal polarization then select Phi pattern, and vertical select theta pattern (or vice versa according to your antenna orientation)
if they are in dBi, you are right, you should add 3dB to calculate the power received by a CP (...)

Some how u have to manage around 50ohm while changing the width, height etc. In my option as far as cst is concern, to normalize to 50ohm would be technically sound but not good enough.
As an example if u normalize to 50ohm and if u manage to get port around 50ohm will give you different results.

Far-field in cst:
3-D plot gives you the contour in three dimensions (by default, the maximum field/power is shown in red). For better understanding, you can include the structure along with the far-field (just right click on the 3-D pattern, plot properties -> show structure). you can also see the polar plot by cutting the plane along theta or
