-14- Abstract of the Disclosure A slot antenna has a substantially reduced ground plane by defining the slot within a loop of a narrow conductive strip, for example a deposited metal, around a slot opening less than one half the wavelength of the intended signal frequency to be received by the antenna. A conductor such as a central conductor of a coaxial cable coupled to the conductive strip on one side of the slot, while another conductor such as the ground shield of the coaxial cable is terminaled at a position across the slot from the central conductor terminal. In addition, the gain and bandwidth of the antenna may be improved by adding a similarly constructed loop or loops of slot antenna in parallel to the first slot to form an overlapping series of loops. Such a modification forms a ground plane with an overlapping series of loop conductors. As a result, the present invention permits a convenient, window mounted antenna assembly, as well as a particularly advantageous combination of window mounted antenna assemblies for a single window panel of a motor vehicle, and is particularly well adapted for use with remote keyless entry systems as well as cellular telephone systems.
