An antenna that radiates in only one direction. Yagi antennas are most commonly used in point-to-point communications. Also called panel or patch antennas.
Antenna Types (PDF) New antenna technologies are being developed that allow an antenna to rapidly change its pattern in response to changes in direction of arrival of the received signal. These antennas and the supporting technology are called adaptive or "smart" antennas and may be used for the higher frequencyLMR bands in the future.
