A window assembly comprises a substrate with a transparent layer that defines an area having a periphery. An outer region devoid of the transparent layer is defined adjacent the transparent layer along the periphery. A conductive element disposed on the substrate and comprises a first portion overlapping an area of the transparent layer and abutting and being in direct electrical contact with the transparent layer. The conductive element further comprises a second portion integrally extending from the first portion and disposed in the outer region. The periphery of the transparent layer delineates the first and second portions of the conductive element. The second portion has an area defining an enclosed slot. A feeding element couples to the conductive element for energizing the enclosed slot as a slot antenna. An energizing element couples to the conductive element for energizing the conductive element to implement a bus bar.

Window assembly comprising conductive transparent layer and conductive element implementing hybrid bus-bar/antenna

An antenna includes a ground element defining a straight edge extending along a first axis. A radiating element is spaced apart from the ground element. A feeding element has a first conductor coupled to the ground element and a second conductor coupled to the radiating element. The radiating element includes two radiating segments extending substantially parallel to one another along a second axis transverse to the first axis with each radiating segment defining a width measured perpendicular to the second axis. The width of one radiating segment is greater than the width of the other radiating segment. A coupling portion connects the radiating segments and includes a straight edge facing the straight edge of the ground element. The straight edge of the coupling portion extends along a third axis that is transverse to the first axis. When combined with a substrate, the antenna is a component of a window assembly.

Multi-band antenna for a window assembly

A window assembly includes a substrate with an electrically conductive transparent layer that defines an area having a periphery. An outer region devoid of the transparent layer is defined adjacent to and along the periphery. An elongated antenna element is disposed in the outer region. A feeding element couples to the antenna element for energizing the antenna element. The area of the transparent layer defines at least two protrusions being spaced apart from one another and extending integrally from the area and into the outer region. The antenna element abuts and is in direct electrical contact with the at least two protrusions. The feeding element couples to the antenna element at a location between the at least two protrusions or at one of the at least two protrusions.

Window assembly with transparent layer and an antenna element

Antenna

A window assembly includes an electrically conductive transparent layer and an antenna element disposed on a substrate. The transparent layer has an area defining a periphery with a plurality of edges. An outer region devoid of the transparent layer is defined adjacent the transparent layer along the periphery. The antenna element includes a first antenna segment and a second antenna segment. The first antenna segment is elongated and disposed in the outer region and spaced from the periphery and extends solely along one edge of the periphery. The second antenna segment extends integrally from the first antenna segment towards the transparent layer such that the second antenna segment crosses a periphery of the transparent layer. A feeding element is coupled to the first antenna segment to energize the antenna element and the transparent layer such that the antenna element and the transparent layer collectively transmit and/or receive radio frequency signals.

An antenna () suitable for receiving circularly polarized RF signals from a satellite is integrated with a window () of a vehicle (), such as a roof window (). The antenna () includes a patch element () disposed adjacent to the window (). Radiating strips () forming at least one dipole pair are disposed below the patch element () and connectable to a transmission line. A coupling element () surrounds the radiating strips () and a dielectric layer () is sandwiched between the patch element () and the radiating strips (). A ground plane () is also disposed below the radiating strip (). A conductive casing () perpendicularly surrounds the antenna () elements while electrically connecting the ground plane () to the coupling element () such that the radiating strips () are generally disposed within a cavity ().

Multi-element cavity-coupled antenna

An antenna for receiving and/or transmitting radio frequency (RF) signals at multiple cellular frequency bands is disposed on a non-conductive pane. The antenna includes a first antenna element and a second antenna element. The first antenna element has a first radiating element and a second radiating element arranged together in an opposing relationship to form a first bowtie shape. The second antenna element is spaced from the first antenna element and has a third radiating element and a fourth radiating element arranged together in an opposing relationship to form a second bowtie shape with a different dimension than the first bowtie shape. A first trace element connects to and extends between said first and third radiating elements and a second trace element connects to and extends between said second and fourth radiating elements. The antenna establishes an electromagnetic coupling for dual band operation at the multiple cellular frequency bands.
