RF Planar splitter and combiner designs for 3.5 GHz WiMax operations using ADS

I am doing my MSc project on "design base station antenna using microstrip rectangular array either series or corporate feed operating on 3.5 GHz for Wimax operation on ADS or FEKO". Can anyone on help me, I will be very thankful to him.

Usually the "best" power combiner/splitter is the Wilkinson type. In patch arrays, since they are usually narrowband, some simple Tees with quarter wavelength transformers do the trick.
