UWB Antenna
Does anybody have good resources about types and structures of UWB antennas?

UWB needs the antennas have broad BW .
So it can use monopole to make it easily.
An introduction for your reference.
Hey
this is a hot topic right now. I think most commonly used antennas are vivaldi and ovals dipoles. I think oval dipoles are nice because they cause very less dispersion to the pulse you want to transmit and their pattern is dipole-like over the bandwidth.
Cheers
thank you very much tomcat_x and arunrock, I was also looking for 3D antenna structures such as the tapered dielectric rod antenna. Do you have any resources about it or other 3D structures?
You can have a look in "Antenna Theory" by Balanis.
You will find information about spiral antennas, which are frequency independent.
:)
Hope this match your request !
Dear All,
It is a very nice presentation by myself. It is helpful.
Best regards,

hi yes , frequency independant antennas are uwb antennas , but for the "modern "UWB radio system which occupy the band from 3.1-10.6GHz, the UWB antennas must have low dispersion as excited by Gaussian impluse , generally speaking , frequency independant antennas are not the good candidaters. Regarding modern UWB antennas , please look at the great book of Dr. Schantz's "The art and science of Ultra-Wideband Antennas" or just search IEEE by author : schantz , there are many papers .
hope this helps

Hi: There is another book on small antennas and UWB antennas. It is by Dr. Zhining Chen and it was just published by Wiley. Dr. Chen did much work on UWB antennas. Please check it.

Have a look at this nice paper: Characterization of ultrawideband antennas using transfer functions

Hey
this is a hot topic right really. I think most commonly used antennas are planar patch Antenna and laoding dipole. I think loading dipoles are nice because they cause very less dispersion to the pulse you want to transmit and their pattern is dipole-like over the bandwidth
does anyone know about uwb spiral antenna design or can u tell me references to search? thanks
Hi:
I tried an antenna example with 4 elliptical shapes and the result is excellent. I could easily achieve S(1,1) < - 10 dB from 3 to 11 GHz. The size is just regular shape. The example is documented in the IE3D manual as an example using the FastEM Design Kit for real-time EM synthesis. Interested users can check it (www.zeland.com). Regards.
Take a look at IEEE.
