antenna dual band 1575MHz Bw=40MHz 2300MHz Bw=50MHz

[sonnh87]

hello every body,
i am a newbie in ads. i have project to design an dual band antenna working at 1575Mhz Bw=40Mhz and 2300Mhz Bw=50Mz. how can i design it?
thank you.

i think first u decide which type of antenna do u want to design e.g. microstrip antenna, PIFA or dipole etc.
after that anyone can help u.

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.

i do as this paper but my S11 look so weird, its graph look likes a line.

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
