  • Method of making antireflective apparatus
    Patent number: 9548451
    Abstract: An apparatus having a reduced reflection from its surface includes a dielectric material and a capacitive circuit analog sheet buried within the dielectric material and configured to produce a reflection that adds out of phase with a reflection from an incident side of the dielectric material. The capacitive circuit analog sheet comprises conductive patches configured to have high impedance for transverse magnetic (TM) polarization.
    Type: Grant

  • Broadband multi-tap antenna
    Patent number: 8643566
    Abstract: An antenna system comprises a plurality of conductors, a combiner, and a plurality of loads. The combiner has an output port. The plurality of loads connects the plurality of conductors to each other in line. The plurality of loads has an impedance equal to a desired impedance for the output port. The combiner combines power received by the plurality of loads at the output port of the combiner.
