An antenna designed to operate on several bands. These antennas often use designs where one part of the antenna is active for one band, and another part is active for a different band. A multiband antenna may have lower than average gain or may be physically larger in compensation.
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.
