Microstrip Rectangular Patch array Antenna

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.

You can get the patch antenna quickly from Antenna Magus. Then add the corporate feed in FEKO. Use the infinite substrate for lowest memory and CPU usage.
