can anybody tell me if there are any antenna design tools availbale for PCB or simple antennas for 868 915 Mhz bands. or does any body have a design for good omin directional antenna's for these bands

thanks

Hi,
Try to use IE3D, best for planar problems. But classic structures on PCB in principle aren't omnidirectional.

sonnet is also another choice

Hi,
You can also use Ansoft Ensemble or HFSS for antenna simulations. Ensemble is like Sonnet, but HFSS is 3D program and you can simulate any structure with HFSS. If you are looking for omni directional antenna, you have to use a dipole antenna.

PIFA or chip antenna maybe a good choice.

EZNEC or MININEC are also alternatives to use

I think that CST MWS is the best choice !

Thank eirp very very ... very much!!!
Very Happy

I believe that CST MWS is the best choice,indeed!!!

We have now started using a chip design which works well

thanks for help

I agree. CST Microwave Studio is the best tool, also for planar antennas.

For simple and omini directional antennas try with WIPL-D.

I think:

CST-MWS for complex antenna structures
MW*Office for simple structures, that connected to some circuits.

With respect,

I think ADS can do something.

not ADS but Momentum ( inside ADS package ) for planar (2d) antennas.

I want to design antenna with antenna software (eg. hp hfss v5.3) but when run post process my computer go in idle mode for long time

You must enter right parameters for EM simulation, every increase numbers of cells increase time of simulation several times.
EM algoritms like FDTD (XFDTD,ZELAND,CST MWS,ANSOFT) are very robust and you must have very fast processor or processors.
If you are beginer try with algorithm based on Method of Moments. One programm based on this algorithm is NEC, it's faster several times then FDTD based programms.

IE3d is a useful soft
don't use HFSS,it lacks accuracy

Accuracy is important of course but;

I hate GUI and manual construction of IE3D.
I too hate graphic of @DS.

CST MWS would be my choise but I have just started to learn.

Hi,

Sonnet 8.52 is a good tool for planar antennas. It is very simple, and this version is very fast. I advice to use it. You can download the light version and see how it works.

Kind regards,
Lkuzu

You may like to use supernec as it is cheap and easy....integration with matlab...

yes you are completely right... nec is much sutable... if you need it its posted in this page!

I use Ensmble (2.5D) but for 3 D structures use CST, probably the best one.

Ansoft has a tool for 2D and 2.5D simulation, not very expensive. ADS has a package called momentum, which can also be used to this kind application. For omnidirection antenna, if it is in 3D, I believe HFSS is an excellent tool. You can of course find some FEM programs to this kind of job. You just need time.
