摘要：An antenna apparatus that can increase capacity in a wireless communicationsystem is disclosed. The antenna operates in conjunction with a station and comprises aplurality of antenna elements (101-n), each coupled to a respective weight controlcomponent (111-n) to provide a weight to the signal transmitted from (or received by)each element. The weight for each antenna element is adjusted to achieve optimumreception during, for example, an idle mode when a pilot signal is received. The antennaarray creates a beam former for signals to be transmitted from the mobile station, and adirectional receiving array to more optimally detect and receive signals transmitted fromthe base station. By directionally receiving and transmitting signals, multipath fading andintercell interference are greatly reduced. The weights are adjusted in a coarse and a finemode. In the coarse mode all the weight control components are jointly adjusted orchanged so that the antenna beam scans through a predetermined sector of a circle untila signal quality metric of the received signal is optimized. The coarse adjustment mode is
followed by a fine adjustment mode during which the weights of are independentlyadjusted to further optimize the signal quality metric.
