Hi,
I have attached the design has CPW with 2 ground element and a feed element. i would like to know what type & how to give feed?





Please help me to Solve the design

hi i attach a CPW antenna model for i hope it useful for you

I have tried this method but simulation shows some error.

Is there any calculation size and impedance for port

whats u mean?
at first i should say this is usual and it work true and may be u do some thing fault
and what u want calculate ? calculate port? thats wrong

Hi,
can anyone Please solve my model

whats your aim ? i added port and simulated it

Hi ,

Thanks Ferdows

It is a dual band antenna operates in Wimax and WLAN band (3.34-4.056 GHz and 4.736 - 5.432 GHz )

Can you able to send methe simulated model to my email rameshkarthik.b@gmail.com
