i decided to design microstrip antenna and i found this paper(Submitted By:- Nandish Mehta). But this antenna working at 1.85 Ghz and 2.37Ghz. how can i change the frequency?

here u deeply go through this paper and then see which parameter used by author for dual frequency band and for widening the bandwidth e.g. slot length and width used for this purpose so u can introduce different type slot for this purpose.

so for doing this u hv gone through the litrature in which u see the dual band antenna design and widening the bandwidth topics and from there u get some techniques by using that u can achieve ur goal........

Frequency is generally changed by changing the dimensions of the patch like width and length.. I havent looked at the paper u submitted but u can try changing dimensions
