    摘要: A time-variant antenna is disclosed that uses a switched capacitor array in silicon to improve the performance and integration options of the time-variant antenna. Parasitic effects of the interface between the on-board antenna and on-silicon switched capacitor array are considered and the antenna is tuned to compensate for these effects. The switched capacitor array provides high linearity, lower cost, and reduced size, relative to prior art antenna implementations.

    摘要: A near-horizon antenna structure includes an upper radiating element having a straight conductive trace disposed on a planar surface of a non-conductive substrate, a rectangular lower radiating element serving as a ground plane disposed on the planar surface, and a feed point provided between the upper and lower radiating elements. When the planar surface is positioned vertically, the far-field effects of horizontal current flowing in opposite directions on the radiating elements cancel to provide an antenna pattern with increased gain in horizontal directions and reduced gain in vertical directions. A flat panel display and a portable communication device are also provided with one or more near-horizon antenna structures integrated therein.

    摘要: Embodiments of a planar asymmetric antenna structure with shifted feed position for multi-protocol operations are disclosed The antenna structure includes two elliptically tapering right and left arms, each with a different radius, and an off-center feed point positioned between the right and left arms. One arm has a smaller elliptical tapering than the other arm and the feed point is positioned closer to one arm than the other arm. A method of synthesizing a multiprotocol antenna pattern is also disclosed. The method includes providing substantially equally surface currents on both arms of an antenna structure to generate a near-horizontal pattern in far-field at a lower frequency band, providing greater surface currents on the right arm to generate a far-field pattern with a large horizontal component at a higher frequency band, and providing greater surface currents on the left arm to generate an asymmetric far-field pattern at a middle frequency band.
