Smart antennas made practical
Erik Öström, Luca Mottola, Martin Nilsson, Thiemo Voigt · 2010
Smart antennas are a specific type of directional antenna able to dynamically control the gain as a function of direction. This contrasts with more traditional directional antennas, where the dynamic ability is missing, and with omnidirectional antennas, which are designed to have equal gain in all directions.
