  • Low-profile embedded ultra-wideband antenna architectures for wireless devices
    Patent number: 7095374
    Abstract: Low-profile, compact UWB embedded antenna designs are provided for use with computing devices, such as laptop computers, which enable ease of integration within computing devices with limited space, while providing suitable antenna characteristics (e.g., impedance matching and radiation efficiency) over an operating bandwidth of about 1 GHz to about 11 GHz.

  • Low cross-polarization broadband suspended plate antennas
    Patent number: 6914563
    Abstract: A suspended plate antenna for broadband applications is disclosed. The antenna comprises a plate radiator, a slot cut in the plate radiator, and a substantially balanced feeding structure symmetrically feeding the plate radiator with respect to at least one midline of the plate radiator.

  • Broadband suspended plate antenna with multi-point feed
    Patent number: 6795023
    Abstract: Feeding structures for suspended plate antennas are disclosed hereinafter for enhancing the impedance bandwidth performance thereof. In any of these feeding structures, a multi-dimensional broadband impedance transformer is integrated with a suspended plate antenna. The impedance transformer electrically connects the radiating plate and feeding probe of the suspended plate antenna. As a result, the impedance bandwidth is increased. Moreover, the multi-dimensional design of the impedance transformer is variable to allow the flexible design and adjustment of the feeding structure.
