14 Jun 2003 5:38 microstrip antenna array

I'd like to simulate a microstrip antenna arrry, which is consist of 16 elementes and the whole size is about 350mm*350mm. What kind of SIMULATOR is the best? MOmentum? IE3D?Ensemble? HFSS?.......
Thanks a lot

MICROWAVE OFFICE IS THE BEST

U CAN USE SEVERAL OTHERS EVEN I DON'T REMEMBER THE EXACT NAMES BUT I SAW SOME ONLY OCCUPYING JUST 2-3 MB

BUT MICROWAVE OFFICE IS THE BEST

Hi,

Have heard of Feko, maybe you would like to give it a try.

i think u can use both HF$$ 9 but is is very slow
IE3d is very good , quit fast ,
u can simulate one patch then u can use CUrview to calculate the array parametters , before u draw it
and its simpler to learn than HF$$

Try a software called emPiCASSO for microstrip array, it is easy to draw!

If your microstrip antenna is a monolayer, u can easily try Ensemble (let's say.. up to 4 or 5 layers).. If your structure is more complex I reccomend to use HFSS or CST (3d codes).
What kind of array are you studying? If u want, I can help u.

I see different idea about simulation of microstrip antenna array.
Is there anyone here who has been simulated a similar project with some EM simulators.If your response is ok please upload it here to vote others

15 Jan 2004 17:54 microwave office microstrip antenna array design

i've spent much time designing and simulating mpa's and arrays (assuming planar design)

the tools i've had at my disposal are hfss, ie3d and cst

by far and away ie3d is the eziest tool & quite accurate

first you can start by designing your element
you can then generate the radiation pattern within ie3d and use the built in array generator to construct an array with control over the array function (that is phase and amplitude distribution) once you have designed your element you can generate these array patterns within 5 minutes.

next if your array structure is small you can generate your entire feeding network & attach to your element. this will allow you to see how your feeding network would effect your radiation patterns and so on.....

if your structure is large i recommend that you design and simulate a section of the array and use what you know about array theory to draw any conclusions.

as far as hfss and cst go you can do these things with either one of these products. however the time spent in building and simulating is an order of magnitude larger. all 3 of these tools generate answers within the same ballpark.

i highly recommend ie3d - however you will need a drafting program such as autocad because the drawing tool is awful other then that you cant go wrong.

in my opinion the best is IE3D

24 Jan 2004 5:17 microstrip antenna array using ads

Hi,
You guys say that one can simulate single antenna element, and then claculate array pattern in either IE3D or CST. I have a question. Do these software account for mutual coupling effect between elements, or they just mutiply single element pattern by array factor? Thx.

06 May 2007 19:50 practical design of microstrip antenna

look microwave office is easy but so primitive you shoul try ie3d or CST or HFSS
also NEC supernec is good it has many ready designs you can start from it and buold up it's matlab interface so you must have matlab installed on your machine

Because machine RAM question, if your model is very large, then you sure to allow for FEKO - MLFMM.

HFSS 10 is easy to use but a bit slow, the tutorial in download at www.emtalk.com/tut_1.htm can be an important help...

CST MWS is the best one

Added after 43 seconds:

Because cst mws is good at electric large antenna

They can do both.

You should consider whether you can accept an inifinite substrate assumption, though. Unshielded Method of Moment (MoM) codes like IE3D and Momentum assume that your substrate (and ground plane) go to infinity.

A full 3D EM Time Domain code, like CST or XFDTD are probably the best full 3D approach to these due to their low memory usage and ability to model non-planar strutures nearby or modeling the edge effects of your substrates. If you are trying to keep your patch substrate as small as possible for practical design considerations, you probably should at least consider the effects of your finite ground plane and finite substrate, and you can't really do this with IE3D or other planar EM tool.

I think that for initial design work, it is good to work with a planar EM tool. Then, when you are considering your real-world packaging, you should probably switch to a full 3D time domain tool like CST or XFDTD.

will you just have antennas and a feed network? or will you have other structures. describe what you want.

As said it depends on what you want to simulate, a good and easy to use choice is CST MWS, it is preferable for planar arrays. For a 3D array HFSS is more suitable i believe but is slower than CST

You can use momentum in ADS for the simulation.

in my case, I used ADS 2008 which integrates EMDS and Momentum to simulate antennas. However, it seems that ADS doesn't support for array antenna simulation with different separated phases.
If your design just uses one stimulate input for array antenna, ADS is very fast.

I think you can define the phase and amplitude of any port separately. Do you mean this? The phase and amplitude of each port is defined separately, therefore you can put the desired phase and scan your pattern.
