Microstrip antenna

hi guys...im studying telecom engrng n i got semester project on ""how to design microstrip antenna operaing at 5.8 GHz" kindly help me in building it from very ba mean tell me how n from where to start n wat r the basic things to consider n etc.....
What make the antenna differ one to another, 5.8GHz, or 2.2GHz ...
Tq.

Essentially all of electromagnetics is described by Maxwell's equations. An interesting feature of these partial differential equations is that there is no fundamental size scale. This leads to some very useful scaling properties. If you have an antenna design that works at frequency f1, but you need it to work at f2, you simply reduce all of its physical dimensions by the factor (f1/f2). The antenna will have all of the same performance parameters at the new frequency (pattern, gain, fractional bandwidth, Q, impedance, etc.). There is one catch. The properties of the underlaying materials that makeup your antenna may be different at the new frequency. The scalability principle I described above assumes the material properties to be constant. Usually this is not a problem.

Good luck!
