Vertically polarized low profile slot antenna on glass beside a conductor

A window of a vehicle, comprising:

• a glass surface;
• a metal frame around the glass surface, wherein the metal frame is over a part of the glass surface and is separated from the glass surface by a separation gap;
• a set of defroster wires in the glass surface, wherein a top wire of the set of defroster wires is separated from a top edge of the metal frame by an antenna region;
• a slot antenna disposed in the antenna region, wherein a portion of the slot antenna resides in the separation gap, the slot antenna having:
• a top side and a bottom side opposite the top side, wherein the top side is located proximate a horizontal cover line of the metal frame;
• a feed point located in a central area of the slot antenna, wherein the slot antenna includes a first slot and a second slot which intersect at the feed point;
• and
• a feed line that extends from the feed point through the separation gap between the metal frame and the glass surface, wherein the feed line connects the slot antenna to a communication device;
• and
• a conductive adhesive layer in the separation gap that electrically couples the portion of the slot antenna to the metal frame.

A vehicle, comprising:

• a window having a glass surface;
• a metal frame around a perimeter of the window, the metal frame defining at least a horizontal cover line and a vertical cover line, wherein the metal frame is over a part of the glass surface and is separated from the glass surface by a separation gap;
• a set of defroster wires in the glass surface, wherein a top wire of the set of defroster wires is separated from a top edge of the metal frame by an antenna region;
• a slot antenna disposed in the antenna region, wherein a portion of the slot antenna resides in the separation gap, the slot antenna having:
• a top side and a bottom side opposite the top side, wherein the top side is located proximate the horizontal cover line of the metal frame;
