| Abstract: |
A glass patch cellular antenna is provided which can be imprinted as a thin film element on the interior surface of an automobile window. The antenna is physically configured to serve as a coupling element for an optional antenna mast which can be mounted externally on the window opposite the antenna. As a thin film element, the antenna can be factory installed and prewired such that the automobile is cellular ready, in that the installation of an external mast is unnecessary to achieve suitable performance. Yet, an external mast can be readily coupled with the antenna in order to enhance the performance capability of the antenna.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. An antenna for receiving and transmitting electromagnetic radio waves from an automobile having a window glass panel, the antenna comprising:
- an electrically-conductive thin film ground element supported by the window glass panel of the automobile and physically spaced from an edge of the window glass panel, the ground element having a substantially rectangular shape and being oriented substantially horizontally;
- an electrically-conductive thin film primary element supported by the window glass panel and physically separated from the ground element, the primary element having a substantially inverted T-shape so as to have a rectangular-shaped first portion oriented substantially perpendicular to the ground element and a rectangular-shaped second portion oriented substantially parallel to the ground element, the first portion being between the ground element and the second portion such that an upper edge of the first portion is adjacent to a central portion of the ground element and physically spaced from the ground element, the upper edge of the first portion being sufficiently close to the ground element such that the primary and ground elements together form an antenna having an efficiency in excess of 50 percent, the primary and ground elements further forming a capacitive coupling element that is configured to capacitively couple to an external mast antenna secured to an exterior surface of the window glass panel.
