  • Fishbone-shaped patch antenna
    Patent number: 6222490
    Abstract: A fishbone-shaped patch antenna structure is provided to increase half-power beamwidth in the horizontal plane of slot coupled microstrip patch antenna containing limited ground plate and limited reflector. This effect is obtained by designing the resonant member to have a toothed portion along either edge of resonant axis thereof.

  • Antenna structure for communication
    Patent number: 6222488
    Abstract: The present invention relates to an antenna structure for communication applications, which is used to increase the half-power beamwidth (HPBW) in the H-plane of the slot coupled microstrip patch antenna with a finite size ground plate and a finite size reflector. The antenna combination according to the present invention comprises a front-plate composed of a curved plate, a flat plate, and several patches. By using the present invention, the half-power beamwidth in the H-plane would be increased.

  • Parabolic reflector antenna
    Patent number: 6184840
    Abstract: This specification discloses a parabolic reflector antenna, which is used as an antenna for signal transmission between the radio communication base station and the mobile terminals. By determining the curvatures and relative positions of a main-dish with a main reflecting surface and a sub-dish with a sub-reflecting surface and means of determining the size of the feedback device and relevant distances in between, the present invention improves the signal reception and emission of the parabolic reflector antenna.
