| Abstract(in English) | Adaptive array antenna is one of the attractive technology for cellular mobile communication systems for increase of capacity. For CDMA cellular base stations, we have designed a distributed configuration of array antenna, which makes it possible to create suitable sector beams and user dependent beams realized with flexible number of or arrange of array antenna elements. This array antenna was designed for tower-top type, which includes its transceiver at backside of its elements, and its configuration has been extended into two-dimensional curved surface. We have built a trial production of this distributed array antenna equipped our original continuous auto-calibration circuits. Several data are shown for confirming experiments of our trial production including its operation under receiver Auto Gain Control (AGC) and transmitter power control. |
