  • Multiband Filter Circuitry, Multiband Duplexer Circuitry, and Related Radio-Frequency System
    Publication number: 20170012763
    Abstract: A multiband filter circuitry utilized in a radio-frequency (RF) system is disclosed. The multiband filter circuitry operates at a plurality of operating frequency bands. The multiband filter circuitry comprises at least a switchable-filtering series. Each of the at least a switchable-filtering series comprises a first terminal coupled between the antenna and the RF processing unit; a second terminal coupled to a ground; and a plurality of switchable-filtering units connected in series, each comprising a filtering unit; and a switching unit, connected to the filtering unit in parallel.

  • Micro-strip antenna with L-shaped band-stop filter
    Patent number: 7889136
    Abstract: A micro-strip antenna includes an L-shaped coupler, a set of micro-strip antennas, and an L-shaped band-stop filter. The set of micro-strip antennas includes at least one rectangular micro-strip antenna unit and a micro-strip line. The rectangular micro-strip antenna unit is coupled to the micro-strip line. The micro-strip line is coupled to the first end of the coupler. The band-stop filter is disposed along a corner of the rectangular micro-strip antenna unit, and is disposed between the antenna unit and the coupler without being physically connected to the antenna unit and the coupler. The width, length, and position of the L-shaped band-stop filter can be determined for the specific band-stop frequency and to optimize its coupling extent with the L-shaped coupler.
