ADJUSTABLE ANTENNA MATCHING |
摘要 |
<p>Wireless communication device tuning an antenna matching circuit responsive to a receive signal quality indicator and, optionally, responsive to a failed access probe is provided. Systems and methods are provided that increase the antenna efficiency in either the transmit frequency or the receive frequency in an idle or access state as needed, based on fading conditions, non-ideal antenna efficiency balance, mobile station forward versus reverse link usage and system forward versus reverse link usage. The antenna efficiency may be changed incrementally or may be optimized completely for the transmit frequency or the receive frequency. The re-balancing is accomplished by tuning the antenna matching circuit. One way to tune the antenna matching circuit is to apply a voltage to a ferro-electric capacitor in the matching circuit, thereby changing the capacitance of the ferro-electric capacitor, thereby changing the impedance of the matching circuit.</p> |
