u slot patch antenna

Hii

I am designing a patch antenna with U-slot to increase the bandwidth. As my previous patch antenna with no slot has bandwidth around 60MHz only and required bandwidth is about 200 MHz.

I am confused on how to determine the dimensions and position on the U-slot on the patch. The frequency of operation is 2.45 GHz and I am using a FR4 board to design the patch which is my requirement.

the Feed method I am using are 1. Microstrip feed line 2. coaxial cable.

Please Help

Thanks
