    • Wireless communication device tuning an antenna matching circuit to favor a receive band efficiency over a transmit band efficiency in an acquisition state. Systems and methods are provided that increase the antenna efficiency in the receive band when the wireless communication device is searching for a synchronization message in order to acquire a communication channel. The antenna efficiency may be changed incrementally or may be optimized completely for the receive frequency. The increase in antenna efficiency in the receive band 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.
    • 调谐天线匹配电路的无线通信设备有利于在采集状态下的发射频带效率的接收频带效率。 提供了当无线通信设备正在搜索同步消息以便获取通信信道时增加接收频带中的天线效率的系统和方法。 天线效率可以逐渐改变,或者可以针对接收频率进行完全优化。 通过调谐天线匹配电路来实现接收频带中天线效率的提高。 调谐天线匹配电路的一种方法是在匹配电路中向铁电电容器施加电压,从而改变铁电电容器的电容,从而改变匹配电路的阻抗。

    • Wireless communication device antenna matching circuit tuning responsive to power control signals, and, optionally, responsive to received signal quality indicators in a traffic channel. Systems and methods are provided that increase the antenna efficiency in either the transmit frequency or the receive frequency as needed, based on fading and environmental 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 antenna system.

    • 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.
