Design of a dual band antenna for mobile comm.

Congratulations for your work, I also work on this topic...
I've been reading your file very fastly.. I think your antenna works in Linear Polarization doesn't it? I want to know if you have tried the dual frequency concept in a CP patch antenna..

Best regards
Lupin

Thanks in advance,have you tried the dual frequency concept in a CP fix antenna and if you have this message?zhangfeilong433@sohu.com

Sorry,
where can I read your file?

I want to design a dual rectangular patch antenna each having 2 coaxial feed and those feed shld be 90 degree out of phase and those 2 antennas may be on the same pcb...
kindly tell me how to excite those 2 antennas for diff frequencies..how to simulate...am using ie3d software

Hai if u have the base paper for this design send it to me i will try to help u.......

do u have any other simulation tool other than IE3D.....?
