Abstract
A dynamically reconfigurable antenna system is disclosed which may be configured with low cost discrete analog components. Particularly, the antenna elements, phase shifters, and beam forming network of the current smart antenna system are configured from RF transmission lines, RF couplers and RF switches in a system which is able to dynamically reconfigure its beam forming signals to point in a direction of greatest signal strength. The smart antenna system may be configured on portable devices to accomplish greater signal reception and transmission when used in a wireless network.
