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： A wireless communications device reconfigurable radiation desensitivity bracket, and associated reconfigurable radiation desensitivity method are provided. The method includes: generating a radiated wave at a first frequency; in response to generating the radiated wave at the first frequency, creating a maximum current per units square (I/units2) through a minimal area of an electrical circuit groundplane; generating a radiated wave at a second frequency; in response to generating the radiated wave at the second frequency, maintaining the maximum I/units2 through the minimal area of the groundplane. Alternately stated, the method controls the distribution of current flow through a groundplane, responsive to radiated emissions, as the wireless device changes operating frequency or communication band. More specifically, the method maintains the maximum I/units2 through the minimal area of the groundplane by coupling the groundplane to a bracket having a selectable effective electrical length.

摘要： A method and device bracket are presented for reconfigurable radiation desensitivity. The method includes: accepting a radiated wave from a source such as a transmitter, antenna, microprocessor, electrical component, integrated circuit, camera, connector, or signal cable; in response to the radiated wave, creating a first current per units square (I/units2) through a groundplane of an electrical circuit such as a printed circuit board (PCB), display, connector, or keypad; accepting a control signal; and, in response to the control signal, creating a second I/units2 through the groundplane. This step couples the groundplane to a bracket having a selectable effective electrical length. Typically, the groundplane is coupled to a bracket with a fixed physical length section to provide a combined effective electrical length responsive to the fixed physical length and the selectable effective electrical length. The coupling mechanism can result from transistor coupling, p/n junction coupling, selectable capacitive coupling, or mechanically bridging.

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.
