== Abstract ==

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 spatial (directional) selectivity and permits to enhance gain in a desired direction and also to lower the influence of a source of interference. 

The capacity of a mesh network can be improved substantially if smart antennas are employed. The smartness of such antennas comes from the intelligent algorithms controlling antenna. The intelligence may include using the ability to steer the beam in order to enhance the node discovery and node self-healing. Beamforming and beam-switching antennas which are '''integrated''' with routing protocols is a new areas of research.

== Replacement for Omnidirectional Antenna ==
The purpose of such antenna is to replace a traditional omnidirectional antenna and provide

This antenna would have a low to intermediate gain due to practical difficulties to obtain both 360 degrees beam steering and high gain at the same time. 

== Antenna Capable of Long-distance Links ==
This antenna is to replace the traditional reflector antennas. The smartness of this antenna is in its ability to identify (for the setup purposes) and keep track of a remote node, and adapt the beamwidth and transmitter power level
