Adaptive antenna apparatus for selecting adaptive control processing according to detected signal quality and radio communication apparatus using the same |
摘要 |
An adaptive antenna apparatus includes two antenna elements and a parasitic element to which a variable reactance element is connected, and selects an adaptive control process according to detected signal quality. A controller executes a first adaptive control process for adaptively controlling respective signals received by the respective antenna elements and outputting the respective signals after the adaptive control as a combined received signal, and executes a second adaptive control process for reactance controlling an element value of the variable reactance element. The controller executes the first adaptive control process. The controller executes a communication process when the detected signal quality is equal to or larger than a predetermined threshold. The controller executes the second adaptive control process when the detected signal quality is not equal to or larger than the threshold.
