Abstract: An electromagnetic coupler that couples antenna signals for a wideband antenna positioned between glass layers of an automotive windshield. The coupler includes a first co-planar waveguide (CPW) formed on one side of a glass layer and a second CPW formed on the other side of the glass layer, where the first and second CPWs are a mirror, or near-mirror, and 180° rotated images of each other. Both the first and second CPWs include a conductive plane where removed portions of the plane define a wide CPW section and a narrow CPW section that are electrically coupled to each other, and where the remaining portions of the conductive plane are ground planes, and where the electromagnetic signals are coupled through the glass layer between the wide CPW sections.

Abstract: A thin film, flexible antenna that has particular application to be adhered to vehicle glass, where the antenna is operable to receive right-hand or left-hand circularly polarized signals from, for example, GPS and SDARS satellites. The antenna is a printed planar antenna formed to the substrate and includes a ground plane having an outer perimeter portion defining a slot therein and having a plurality of sides. A T-line tuning stub extends from one of the sides into the slot, a curved spur-line tuning stub extends from a corner where two sides of the perimeter portion meet and extends into the slot, and a radiating element electrically isolated from the perimeter portion extends into the slot. The perimeter portion is operable to generate circularly polarized signals to be received by the radiating element where the tuning stubs provide phase tuning of the circularly polarized signals.

Abstract: A multi-antenna ground plane structure in a vehicle includes a first ground plane to be electrically connected to a fascia chassis. The fascia chassis is a portion of the vehicle covered by a fascia. A first side of the first ground plane seats two or more antennas. The multi-antenna ground plane structure also includes one or more additional ground planes affixed to a second side, opposite the first side, of the first ground plane. One of the one or more additional ground planes is attached to one or more antennas such that the one or more antennas is oriented opposite an orientation of the two or more antennas seated on the first ground plane.

Abstract: A thin film, flexible antenna that has particular application to be adhered to vehicle glass, where the antenna has a wideband antenna geometry and is operable to receive right-hand or left-hand circularly polarized signals from, for example, GPS and SDARS satellites. The antenna is a printed planar antenna formed to the substrate and includes a ground plane having a slot formed therein and a tuning sleeve having a vertical portion and a horizontal portion. The planar antenna further includes a radiating element positioned adjacent to the tuning sleeve and including a feed portion positioned within the slot, where the radiating element includes a first horizontal portion and a second horizontal portion extending from a vertical portion towards the vertical portion of the sleeve. The ground plane is operable to generate circularly polarized signals to be received by the radiating element where the sleeve provides phase tuning of the signals.

Abstract: An antenna assembly including a planar antenna formed on a dielectric substrate and a frequency selective impedance surface formed on the substrate and at least partially surrounding the antenna. The frequency selective impedance surface receives surface waves propagating along the dielectric substrate generated by the antenna, where the impedance surface mitigates negative effects of the surface waves by converting the surface wave energy into leaky-wave radiation, and also possibly providing some control of the radiation gain pattern of the antenna. In one embodiment, the dielectric substrate is vehicle glass, such as a vehicle windshield.
