摘要： An apparatus, system, and method dynamically adjust an antenna network frequency response in accordance with an operation mode of a half duplex call. One of a plurality of antenna network configurations is selected based at least partly on the half duplex operation mode which comprises a talk mode and a listen mode. When the portable communication device is in a listen mode, the antenna network is tuned to a reception configuration which results in a reception efficiency that is greater for at least a portion of a reception frequency band than the reception efficiency resulting from at least one other antenna network configuration. The antenna network is maintained in a default configuration unless antenna adjustment conditions are met. In some situations, the antenna network is set to a transmission configuration to improve transmission efficiency relative to the default configuration.

摘要： A system and method is provided for tuning a Global Positioning System (GPS) antenna matching circuit in a portable wireless communications device. The method includes accepting a first matching circuit tuning value, measuring satellite vehicle (SV) carrier-to-noise ratio (C/N) associated with the first tuning value and a first search time interval, measuring the SV C/N associated with a next tuning value, and selecting the tuning value associated with the highest SV C/N to tune the matching circuit. In one aspect, the method further includes comparing the SV C/N to a first minimum threshold. If the first tuning value SV C/N exceeds the first minimum threshold, then the method measures the SV C/N associated with the next tuning value. Otherwise, a default tuning value can be selected to tune the matching circuit.

摘要： 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.

摘要： 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.

摘要： 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.
