microline antenna design

hi

does anyone know any information regarding design of small size patch antenna in the 400 to 800Mhz frequency range
any help would be highly appreciated

thanks

Try with rectangular microline antenna with notched patch and using stripline feed.
and used the half ground plane .

you can design and optimized by using CPF coplaner feed also.

I used this design my CST microwave studio simulation. version 5
