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.

摘要： Various resonant modes of a multiresonant antenna structure share at least portions of the structure volume. The basic antenna element has a ground plane and a pair of spaced-apart conductors electrically connected to the ground plane. Additional elements are coupled to the basic element, such as by stacking, nesting or juxtaposition in an array. In this way, individual antenna structures share common elements and volumes, thereby increasing the ratio of relative bandwidth to volume.

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 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： An antenna system comprises a receive diversity antenna system and a configurable antenna arrangement. Incoming signals are received through the receive diversity antenna system and outgoing signals are transmitted through the configurable antenna arrangement. A controller generates control signals to adjust the configurable antenna arrangement to change the transmission performance characteristics of the configurable antenna arrangement. The configurable antenna arrangement may be a smart antenna, a plurality of antennas, or a configurable antenna where transmission characteristics change in response to control signals.
