	Smart antenna is an antenna that is capable of adapting its properties to satisfy particular goal(s). The goals may for example include radiation pattern shaping (beamforming/beamswitching). The beamforming provides ~~spacial~~ (directional) selectivity and permits to enhance gain in a desired direction and also to lower the influence of a source of interference.
