    摘要： A wireless communication device is provided having an infrared transducer integrated on certain components. If the wireless communication device has an external antenna, the infrared transducer may be positioned at the tip of the antenna; if the wireless communication device has a clam-shell construction, the infrared transducer may be positioned within the hinge structure. In either position, the infrared transducer can establish line-of-sight connectivity and fill a space previously considered unusable for functional components.

    摘要： This document describes designs and techniques for directly feeding an unbalanced transmission line with a balanced antenna using Composite Right and Left Handed (CRLH) and balun structures. According to various examples, first and second radiating elements, first and second antenna structures, or first and second portions of an antenna structure can provide a left-handed (LH) mode resonance and a right-handed (RH) mode resonance. A feed port can provide an unbalanced signal, and a balun structure can be coupled to the first and second radiating elements, first and second antenna structures, or first and second portions of an antenna structure, to adapt the unbalanced signal from the feed port to a balanced signal for coupling to the first and second radiating elements, first and second antenna structures, or first and second portions of an antenna structure.

    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： An antenna system includes a plurality of antenna feed points operatively coupled to one or more antennas and a controller for selecting at least one of the antenna feed points based on the operating environment of the antenna system. When the antenna system is employed in a mobile wireless device, selecting a particular antenna feed point can modify the device's surface current distribution to improve the antenna system's performance over the effects of near field conditions.
