  • Communication system and method utilizing an antenna having adaptive characteristics
    Patent number: 5680142
    Abstract: An apparatus, and an associated method, for facilitating reception and transmission of signals in a communication system, such as a cellular communication system. An antenna having an antenna pattern adaptively responsive to propagation characteristics extending between communication stations of the communication system. The antenna pattern of the antenna is selected responsive to the propagation characteristics. When the propagation characteristics are indicative of a channel exhibiting only insignificant multipath components, the antenna pattern is selected to be highly directional, and when the propagation characteristics are indicative of a channel exhibiting significant multipath components, the antenna pattern is altered to become less directional.
