摘要： A capacitively-loaded loop antenna and corresponding radiation method have been provided. The antenna comprises a transformer loop having a balanced feed interface and a capacitively-loaded loop radiator. In one aspect, the capacitively-loaded loop radiator is a balanced radiator. In another, the transformed loop and capacitively-loaded loop radiator are physically connected. That is, the transformer loop and the capacitively-loaded loop radiator have a portion shared by both of the loop perimeters. Alternately, the loops are physically independent of each other. In one aspect, the perimeters have a rectangular shape. Other shapes such as round or oval are also possible. In another aspect, the planes formed by the transformer and capacitively-loaded loop radiator can be coplanar or non-planar, while both loops are orthogonal to a common magnetic near-field generated by the transformed loop. The radiator has a capacitively-loaded side, or capacitively loaded perimeter section, depending on the shape of the perimeter.

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.
