Abstract
The antenna system and method for dynamically controlling radiation patterns provides an assortment of radiation patterns to increase the performance of communication systems, such as trunking communication systems and cellular communication systems. One embodiment of the antenna system permits a user to manually select a desired radiation pattern from the assortment of radiation patterns. For example, the user may manually select a desired radiation pattern via a graphical user interface of a general purpose computer, or via a conventional telephone. Another embodiment of the antenna system and method tailors radiation patterns in response to factors such as the locations of mobile units, the channel assignments of mobile units, and the transmissions of particular mobile units.
