which is the best antenna design software for arrays

wael.elshennawy · Jul 21, 2008

Hi All

Kindly note that one can either choose between Zeeland (IE3D) or HFSS.

Wipel-D
They have special tool for array design
Also It is much cheaper compair to HFSS

hi,

Microwave CST studio is available, like HFSS it is also bit costly. FEKO software/Empire 3D is also there.

But i feel HFSS is ther best

How much cost CST and HFFS?

Thanks

laseetha · Jul 23, 2008

HFSS costs around 7- 9 lakhs for educational purposes. dont know about CST.
IE3D also costs around 5- 7 lakhs for eduactional purposes

7 lakhs correspond to $16000 US dollar?

For business, that number will multiply for how much? 5x?

Thanks for the information.

I told that in our indian currency INR ;
and approximately 45 INR = 1$
the tariff may vary from country to country

hi,

Microwave CST suite BASIC PRICE (Before few months back it was like this)

Full processor with 1 solver module (T or F or E) 12Lacs
Full processor with 2 solver module (T+F or T+E or F+E) 18.5Lacs
Full processor with 3 solver modules (T+F+E) 26.5 lacs.
Front End 6lacs (Front end is mandatory)

other options

IGES Import/Export 1.65Lacs
Extended DXF import/Export 1.35lacs
GDS II Import 1.35 lacs
Gerber import 1.35 lacs
Spice par. Extraction 1.65lacs
Hugo interface 1.65lacs
parallel version 1.15lacs

Karnataka VAT @ 4% extra........

or you can contact E-mail: step@stepelectronicsindia.com, srinu@vsnl.com

or you can quote directly in the company websit address

about HFSS around 30lacs (my guess). For education it was around 8.5lacs for our institure (for business purpose, as jhonnss told it is 4.5X-5x)

I dont know for sure, only give an estimate for the business purpose.

But these software are very expensive, yes, they´re professional softwares targeted for big companies, but for people like me, who want´s to start a small business for antennas at Wireless 2.4/5Ghz, there´s no way i can afford that prices.

Anyone knows if it´s legal to buy a second hand old version of HFFS or CST and use it for business?

chandregowda · Jul 24, 2008

hi,

u are right sir, its very difficult for a growing company to afford it (as in our case).

why cant you try other options
1. collabaration with other company/educational institute which is having this antenna design software. this is working good for us with a educational institute.
I am roaming here & there for design & simulations......
2. try to download the old versions from the net itself. they are available, you can try at ur own...... but u cant use in the company. if any thing goes wrong they will fire you like any thing ( fine is around Rs.80 lacs for a software that costs 40 lacs. this happened in one of my friendz company for business purpose. they were using unlicensed version)

I think it is really worthwhile to check out the Agilent EEsof products
http://eesof.tm.agilent.com/

They offer the largest spectrum in EM solutions from Method of moments to FDTD to FEM

They have the advantage of being strongly inetgrated in a full RF design platforms like ADS and Genesys.

EMDS for ADS is sold at very competitive prices beating the competition
http://eesof.tm.agilent.com/products/emds_main.html

AMDS for ADS is totally focussed on antenna design

i think NEC2 antenna simulation software is available freely in the net

any license required for NEC2 antenna simn software?

laseetha · Jul 25, 2008

no license needed

chandregowda · Jul 26, 2008

hi

ok, i try that.....

none of this software seems to me specific for array.

I saw other posts suggesting CST, HFSS, IE3D for array simulation, but all these softwares are more suited to solve electromagnetic problems ! I mean that usually array of 10, 100 1000 o even more elements cannot be simulated "efficiently" by means of this software (computation time and memory grows quckly and then the accuracy decay). Moreover they are more or less general purpose, that is good, but when you are trying to optimise a specific problem they can not make use of "specific problem characteristics", infact usually they make use of optimiser that are something like global searh (e.g. genetics) that are also quite general purpose.

have a look at **broken link removed** for array tools. Despite the web site is not complete you can find a lot of tools foe array.

Bye, bye.

Have you looked at AMDS from Agilent Technolgies? They call it Antenna Modeling Design System and is supposed to have flexible Python scripting to generate conformal array structures efficiently. Then they use Nvidia graphics cards to accelerate the FDTD simulation by up to 50x when compared to HFSS.
It is rumored that the large phase arrays used by the US weapon companies are designed with AMDS. Check it out http://eesof.tm.agilent.com/products/amds_main.html
