MULTIBAND VEHICLE ANTENNA

摘要

A road vehicle antenna comprising a slot defined by an aperture in electrically conductive structure of the vehicle body and a further conductive structure disposed in said 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 being 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.
