    摘要： An antenna device includes a substrate having a first surface and a second surface. A first conductive layer is formed on the first surface of the substrate, the first conductive layer having a perimeter defined by one or more shapes having straight or curved edges. The first conductive layer defines a slot and a coupling gap, and also includes a top ground. The coupling gap separates the top ground from a metal plate region. A second conductive layer is formed on the second surface of the substrate, the second conductive layer including a bottom ground. The slot, coupling gap, first conductive layer, and substrate form a composite right and left handed (CRLH) structure.

    摘要： A system includes a plurality of band pass filters to pass signals in separated frequency bands to or from an antenna. A matching network provides characteristic impedances. The system is designed such that the configuration of the matching network and BPFs provides high impedance to the band pass filters for those routing paths other than the band pass path as these routing paths do not transmit or receive the signals at this particular pass band. The system is further designed such that the configuration of the matching network and BPFs provides minimal insertion loss for the band pass path of for transmission and receipt of signals at this particular pass band, where each routing path has a corresponding pass band. The matching network is for coupling to an amplifier, when frequency separation is needed at the output of the amplifier to the BPFs. In one embodiment an impedance network tunes the impedance by using varying length transmission lines.
