  • Integrated loop antenna for vehicular applications
    Patent number: 7212167
    Abstract: A vehicular screen antenna includes a conductor extending on a dielectric, such as a window. The conductor is configured as a loop having entry and exit segments, the loop being positioned generally centrally on the dielectric. The entry and exit segments extend proximate each other from the loop towards a first edge of the dielectric and are oriented on the dielectric so as to extend generally vertically when the dielectric is fitted to a vehicle.
    Type: Grant
    Filed: July 24, 2003
    Date of Patent: May 1, 2007
    Assignee: Harada Industry Co., Ltd.

  • Multiband vehicle antenna
    Patent number: 6498588
    Abstract: A road vehicle antenna includes a slot defined by an aperture in an electrically-conductive structure of the vehicle body and a further conductive structure disposed in the aperture, and a plurality of antenna feeds positioned so that the slot is excited in a first mode and simultaneously in at least one higher-order mode. The feeds are combined such that the antenna exhibits a diversity of radiation patterns in excess of the number of feeds. The antenna may be formed by a conductive area of a window and the surrounding window frame.
