Definition - What does Smart Antenna mean?
A smart antenna is a specific type of digital antenna that has capabilities related to tracking or handling signals. These types of antenna setups are often used in signal processing, radar and telecommunications, and are evaluated by groups like the IEEE.
Smart antennas are also known as adaptive array antennas.
Techopedia explains Smart Antenna
Smart antennas can be part of systems like reconfigurable broadband and next-generation wireless systems. Solutions like beamforming help to direct signal transmission in specific ways. Two different types of smart antennas, switched beam smart antennas and adaptive array antennas, work in different ways. In general, smart antennas help to specialize signal transmissions for efficiency and other benefits. They "beam" signals in targeted ways, to make the generalized antenna output more precise.
