help, 2.5 - 2.7 pcb patch antenna for wimax

Hi!, i want to build my own patch antenna for my huawei echolife BM622, which operates at 2.5 - 2.7 ghz. I have no background on telecommunications, so i need some references like ebooks,tutorials,software or a schematic diagram/layout of the antenna will be much appreciated. Hope you can help me with my problem. Thanks in advance

You can look at Balanis's book: "Antenna Theory: Analysis and Design". There is explained a design procedure for patch antennas.
Just to make your start a bit easier, the golden rule for rectangular patch antennas is that their length must be half a wavelength.

By the way,
Here you have a useful patch calculator.
You can take these results as starting point for an optimization using a full-wave simulator.
