  • Mobile communication handset with adaptive antenna array
    Patent number: 7530180
    Abstract: A wireless mobile handset includes an antenna array. The antenna array includes a passive element disposed on a first portion of a dielectric substrate and an active element disposed on a second portion of the dielectric substrate. The passive element is configured to operate in a reflective mode to produce a bi-directional radiation pattern.

  • Mobile communication handset with adaptive antenna array
    Patent number: 7190313
    Abstract: A mobile communication handset includes at least one passive antenna element and an active antenna element adjacent to the passive antenna elements protruding from a housing. The active element is coupled to electronic radio communication circuits and the passive antenna elements are coupled to circuit elements that affect the directivity of communication signals coupled to the antenna elements.

  • Broadband circularly polarized antenna
    Patent number: 5952982
    Abstract: A wideband circularly polarized antenna comprises a crossed-element spatial quadrature arrangement of log-periodic antenna elements. The orientation of one of the antenna arms of each diametrically opposed pair of arms is reversed from four port rose configuration, so that the antenna arms of each of the two pairs of elements have mutual mirror symmetry. As a result, each pair of antennal arms may be fed by phase quadrature ports of the same ninety degree hybrid, thereby significantly reducing the complexity of the feed network.
