Embodiment Construction

[0073] For better understanding, the scale of each component in the drawings may differ from the actual scale. In this specification, using a three-dimensional orthogonal coordinate system in three axis directions (X-axis direction, Y-axis direction, Z-axis direction), the width direction of the frequency-selective decoated portion is defined as the X direction, and the thickness direction is defined as is defined as the Y direction, and height is defined as the Z direction. The direction from the bottom to the top of the frequency-selective decoated portion was defined as the +Z-axis direction, and the opposite direction was defined as the -Z-axis direction. In the following description, the +Z-axis direction is referred to as upward and the -Z-axis direction may be referred to as downward.

[0074] refer to figure 1 , describes the first embodiment of the present invention.

[0075] Such as figure 1 As shown, the glazing unit 1 comprises a glass panel 10 with low reflect...

Abstract

The present invention discloses an improved a glazing unit comprising a glass panel which is low in reflectance for RF radiation, a coating system which is high in reflectance for RF radiation disposed on the said glass panel and creating onto the glazing unit a dual band bandpass filter. The glazing unit further comprises at least one frequencies selective decoated portion of the coating system extending along a plane, P, defined by a longitudinal axis, X, and a vertical axis, Z; having a width, DW, measured along the longitudinal axis, X, and a length, DL, measured along the vertical axis, Z. The at least one frequencies selective decoated portion comprises a first decoated element comprising a plurality of unit cells forming a regular grid. The at least one frequencies selective decoated portion further comprises a plurality of second decoated elements wherein a second decoated element is placed in each unit cell of the first decoated element and wherein no second decoated element is in contact with the first decoated element.

Description

technical field [0001] The invention relates to a built-in glazing unit with a frequency selective coating. Background technique [0002] The present invention relates generally to providing a surface with frequency selective transmission properties on a coated glass panel and, in some embodiments, to an embedded glass panel having a coating system such as a solar control coating deposited thereon Provide this surface. [0003] Antennas for receiving and or transmitting radio-frequency (RF) waves are often incorporated in glazing for building and automotive applications. These can be implemented eg as a conductive film deposited on the mounting glass or as metal lines or strips attached thereto. In laminated glazing, which typically includes two or more glass panes bonded by a polymer interlayer, the antenna may be located within the laminate, ie, within the interlayer or on a glass surface contacting the interlayer. [0004] Additionally, in many cases, additional equipm...
