  • Patent number: 5959586
    Abstract: An antenna exhibiting a wide bandwidth, a low standing wave ratio, and a substantially omnidirectional radiation pattern. The antenna includes a sheet-like antenna element having a feedpoint, and an electromagnetic characteristic having non-uniform variation with distance across the element from the feedpoint. One use of the antenna is on a windshield.
    Type: Grant

  • Patent number: 4697191
    Abstract: Disclosed herein is an antenna of simplified and integral construction which comprises a pair of electrical conductors defining a pair of antenna elements or arms aligned in substantially mutually orthogonal longitudinal alignment along a substantially horizontal plane, the longitudinal dimension of the antenna elements corresponding to about one-half the in-medium wavelength of a preselected frequency. An electrically balanced transmission line is formed integral with the electrical conductors and establishes electrical communication between the antenna and a remote RF receiver/transmitter. The antenna has general applicability both as an above-ground antenna and as a buried antenna.
