Hi
I need to design a wide band antenna covering the range from 50 meg to 4 Ghz.
I searched alot and I found some people talk about active antennas wipe or telescopic . Also they divide the band in two regions or more.
I also found a magic one but its details are not published called "fractal antenna"

I need the antenna to be in small size as possible.
I appreciate if any one here could help

Thanks
Regards
Haytham
 

Re: Wideband antenna

hi Haytham,
i suppose the UWB antenna, fractal UWB antenna being one of its type, are suitable for you.
i don't know what other requirements are needed for the design.
 

Re: Wideband antenna

hi haytham,

I Think u can go for Sierpinski Multiband fractal antenna.

With this i've attached a paper regarding Sierpinski Multiband fractal antenna.

I think it'll help u.
 

Re: Wideband antenna

hi
balaguru thavamani : no paper is attached
would u plz attach it again

DrunkBear : I would be gratful if you have details on how to design a fractal antenna

Re: Wideband antenna

I couldnt able to upload because its already uploaded in this forum.

Paper detail is

On the behavior of the Sierpinski multiband fractal antenna

Antennas and Propagation, IEEE Transactions on
Volume 46, Issue 4, Apr 1998 Page(s):517 - 524

Summary:The multiband behavior of the fractal
 

Re: Wideband antenna

hi haytham,

i suppose you could get ABC about it and could try to design one after you read some papers about fractal antenna(as what balaguru thavamani suggested, e.g)
good luck!
 

Re: Wideband antenna

Hi guy
I think fractal are multiband antennas but never been designed for such a long wideband range, although they are good enough for multiband systems.

I think u need to think a simple circular disk monopole will be a good choice in you case.

Re: Wideband antenna

Hi snkhan
Would you please help me with more details about circular disk monopole.
If you have some design papers, it would be great
