hi every body

I am going to design a planar square 4 element array of hellical antennas in x band. anybody can help me to draw a helical antenna in HFSS simply?
and is there a better simulator for this kind of antenna?
another question, can HFSS gather data to form a array from a single antenna run or I should export the s-parameters to another program?

thanx a lot :)

a planar square antenna should be no problem at all with HFSS. Just sketch out the boundaries and corners of your antenna on a piece of paper. Create rectangles accordingly and unite them. If you are more familiar with AutoCAD, you can draw it in there, export the file into a sat file and import that into HFSS.

HFSS is fine for this kind of antenna

HFSS has a helix generator so that should be quite quick to draw. Also, HFSS allows you to simulate one antenna and then see the radiation pattern of an arbitrary array - you just enter the spacing from one antenna to the next.

I was also been designing a similar problem wass you been able to design and simulate that 4 array helical antenna.
If so i need your help in that if you can share it with me .

Regards
shahid

hi,

actually, you may want to try MICROSTRIPES.
recent post http://www.flomerics.com/news/news_deta ... newsId=402

and moreover, company like sarantel is using it for complex PowerHelix™ antennas....
microstripes.com

good luck

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
