ABSTRACT:
A dipole antenna for use in motor vehicles is provided. The antenna comprises a primary linear element, a secondary element extending from the distal end of the primary element in a generally perpendicular manner and a tertiary element extending from the primary element intermediate to the distal end and a breakpoint in the primary element. The antenna generally represents an "F" shape and is electrically insulated from ground. Further, the antenna may be closely spaced to a ground plane portion of the vehicle to which the receiving device is grounded, thereby providing a directional antenna useful in a passive entry system.
