Adaptive array antenna system, adaptive array antenna control method, and radio apparatus

摘要

PPROBLEM TO BE SOLVED: To provide an adaptive array antenna system suitable for realizing downsizing, cost reduction and power saving. PSOLUTION: The antenna system includes an antenna unit 1 having a plurality of directivity, and a summing unit 5 for adding each output signal of the antenna unit 1 totally. The directivity of the array antenna is controlled by estimating the coming direction of the desired wave from the added signal. PCOPYRIGHT: (C)2005,JPO&NCIPI
