A system and method for a smart antenna is provided. A system includes a receiver and a transmitter. The receiver includes a pair of antenna path. The first path includes a variable phase shifter and a variable gain amplifier, and the second path includes a variable gain amplifier. For beam forming, the phase shift value of the phase shifter is changed. For example, the phase shift value is changed sequentially within 10-18 packets. For example, the phase shift value is changed in accordance with certain equations within 4 packets. The phase and gain of a receiver mo de is applied to a transmitter mode.
