hi,all
i tried to simulate antenna according to "CPW-fed crescent patch antenna for UWB
applications by M.-E. Chen and J.-H. Wang"
but my result is different
If anyone can simulate. please help me
thanks
 

Hi, llololl:

It seems to me you have built the shapes correctly. However, you have included a GND on IE3D. The GND will suppress the wide band charactersistics of the antenna. Please change the No.0 substrate's conductivity to 0 and you should get good results. Good luck!

Regards,

Hi, llololl:

I corrected the gnd and results are excellent. It takes couple minutes for a wide frequency range from 1 to 12 GHz. It is an excellent example on IE3D. Regards.
