Re: Ultra wide band antenna design

sir the circular uwb antenna u hav designed have satisfactory gain up to 6 Ghz abov 6 Ghz the antenna gain is not gud.the antennas i hav designed hav same problm.pls sir upload any type of uwb antenna which hav falt gain of 4 or abov dB over entire uwb range as 2-10 Ghz.sir pls upload as early as possible i wil be very thankful to you

sir pls chk uploaded antenna and remove the notch.reply as soon as possible.rely thankx

sir firdows rely as soon as posibl

Hi bro, I'm trying to design an exactly similar antenna (trapazoidal tooth log periodic antenna) for 8-16GHz, I have seen number of papers by Isbell, DuHamel, Ergul and others but still I have confusions about the design. BROADBAND LOGARITHlVIICALLY PERIODIC.pdf is the file attached for example, where at page 3 , R1=10inch is smthing i'm unable to understand plus I'm having extreme difficulties in designing this type of structure with Taw=0.707, sie=45 deg, beta=10 deg and alfa = 60 deg, .I'm using the CST Microwave environment for simulations. Feeding also seems to be another issue cming up next , so do u have any suggestions or any similar simulation models in CST or HFSS or any other environment, do let me know please.
Best Regards
Kamal

hi there could you please forward these papers to me.
my e-mail is abd890@yahoo.com

thanks

dear friend send your papers related Omnidirectional UWB antenna design,soon thank um that will be useful for my thesis
send to my mail id : saidaiahbandi@gmail.com

Hi saidaiahbandi ;

I have forward them to your email... check if you have received them...

regards

If you google a bit, there are a lot of information on UWB antennas.

First you need to decide whether your antenna needs to be directional or omni-ditectional types...

For omni-directional there are many monopole antenna designs available...
for directional types, many members have replied with different types of antennas.

JPIER is a good free source for antenna papers. give a try... there are so many interesting UWB antenna designs have been published there...

cheers,

Hello AngolaX ,
I am working in a project about design of UWB antennas for WLAN applications
Can you send the publishes you have about it please and what type do you advice me to do, which cover bandwidth 3.1GHz-10.6GHZ

Regards,
Mansour

we have difference model of antenna for this range which one of them do u want to design?
