Radio transmission region in metallic panel
First Claim
1. A panel comprising:
- a metal layer in electrical communication with a source of electricity; and
an aperture in said metal layer comprising a plurality of openings arranged in a pattern such that said openings are approximately parallel to each other and the respective lengths of said openings generally increase from one side of said pattern to an opposite side of said pattern, said aperture oriented such that electricity is adapted to pass between said openings from a first portion of said metal layer to a second portion of said metal layer;
wherein said aperture is adapted to enable the transmission of a radio frequency signal through said metal layer.

Abstract
A region in a metallic panel that facilitates the transmission of radio frequency signals. The metallic panel may be included in a window such as the window of a vehicle or building. For example, the metallic panel may be used for heating or to reflect infrared radiation. An aperture is formed in the metallic panel to enable radio frequency signals to be transmitted through the metallic panel. The design of the aperture may be selected to enable the transmission of the desired frequency band. In an embodiment in which the metallic panel is used to conduct electric current, the aperture may be oriented such that the current may flow between the openings of the aperture. Accordingly, there may be uniform heating across the metallic panel without blocking the transmission of radio frequency signals in the desired frequency band.
