HI Xeeshan:

Let me give you a little jump start here, whille you're checking out those sources.

Beam formation of ANY antenna is by means of wave interference. Depending on the relative phasing of two or more radiators, the field at a given distance will either reinforce or cancel. The number one rule of ALL beam forming antennas: There's no such thing as a free lunch. In other words, the entire power delivered to an antenna does not change regardless of how high the antenna GAIN. An increase in signal in one direction always results in a DECREASE in signal in another direction. All that a beam-forming antenna can do is REDISTRIBUTE the power.

When you get to the point where you understand the basics of antennas, I can show you some POWERFUL antenna modeling tools, so you can predict radiation patterns with great accuracy.

This is a fun field....and there isn't a lot of competition!
