vivaldi antenna

I know some uwb antennas such as cone antenna , horn antenna, and vivaldi antenna . Who know some other uwb antennas , let's discuss it toghether

spiral uwb antenna

Check out this article:

"Novel antennas for ultra-wideband communications"
by N. Fortino, G. Kossiavas, J. Y. Dauvignac, R. Staraj

in Microwave and Optical Technology Letters, Volume 41, Issue 3 , pp. 166 - 169

based on a triangular (bowtie) monopole...Completely different from typical UWB antenna types...

s11 parameter graphs for uwb antenna

I am working on Planar UWB Antenna such as SINUOUS, LOGPER and Spiral Antennas.

uwb antenna design

i read about an ultra wideband antenna, called "fish eye" antenna, it was a kind of microstrip antenna, and it was used in puls radar and puls communication. it has 2 octave bandwidth

uwb helical antena

Can you upload any doc about fish eye, please

uwb antenna vivaldi

I am working on Planar UWB Antenna such as SINUOUS, LOGPER and Spiral Antennas.

Hi KMPA,

I am very interested in sinuous antennas and their feed networks... can you please give me any information on how i could design the tapered balun.

Hi Dear jafargholi!

You'd better use CST in order to simulate the ULTRA WIDEBAND ANTENNA, cause the frequency range is so large.

Thanks!

Added after 5 minutes:

Hi Everyone!

I know some other UWBA too, such as Helical Antenna, Spherical Antenna, Elliptic Antenna, Four Square Patch Antenna, Drop-Eye Antenna and Spiral Antenna.

Thanks!

ultra wideband helical antenna

hi all,i simualte some uwb antenna with bandwidth 150% if u need it ,i ready to upload them

KMPA?
What do u wanna show? the live-show-antenne?
So do sthg more serviceable !

horn antenna broadband in hfss

Hi, all:

There are many kinds of structures to achieve UWB performance. The critical point is that you need to give it enough volume for the field. The physical part can be low profile. However, you should give it enough space in the proximity. I tried one antenna with 4 elliptical shapes, I can easily achieve S11 < - 10 dB from 3 to mroe than 12 GHz. Attached is some graph showing the shape and the s-parameters realized by the FastEM Design Kit on IE3D. Interested users can find the structure from the IE3D evaluation license (www.zeland.com). The antenna is not patented or I am not sure whether there is any organization patended such an antenna. Its performance is excellent. I am from Zeland. Regards.

broadband conical spiral antenna

hi all,i simualte some uwb antenna with bandwidth 150% if u need it ,i ready to upload them

here is one of them

conical spiral antenna design uwb

hello all
i'm simulating equiangular spiral antenna with hfss
for my undergraduate thesis. i must match the antenna's input impedance to 50 ohm. does anybody here know about ways to match it? i mean playing with geometry or stuff like that. it must operate within 2-18 ghz. so if we use balun it'll be narrowband and i'll fail

any help is appreciated. if u want to know about spiral antennas i can help a little too. just leave a message.

wu-king dipole

Hi ayy2023

You may want to check out the paper entiled "Broadband Microstrip-Coplanar Stripline-Fed Circularly Polarized Spiral Antenna" from IEEE APS 2006. You can design a broadband balun and still get the wideband performance of your antenna.
Hope it helps.

hi Mansour_M

are you have some articles or simulation files for Spherical Antenna, Elliptic Antenna, Drop-Eye Antenna

i wonder that simulate them.
best regards

spiral uwb antenna

Hi there

There are Wu-King antennas too. But with less efectivity (resistive sheet). On the other side Wu-King based structures are extremly wideband.
