Abstract
The disclosure relates to an antenna for a glass roof of a vehicle. The antenna can comprise a radiator for radiating electromagnetic waves. The radiator can be configured to be disposed between two glass layers of the glass roof. The radiator can be configured for feeding a signal to a receiver. The antenna can be substantially flat.
Claims20
An antenna for embedded in a glass roof of a vehicle, wherein the antenna is substantially flat and is configured as a global navigation satellite system (GNSS) antenna, and wherein the antenna comprises:
- a radiator for radiating electromagnetic waves, wherein the radiator is:
- disposed between two glass layers of the glass roof,
- configured for feeding a signal to a receiver, and
- configured for radiating the electromagnetic waves in at least three frequency bands of GNSS;
- and
- a reflector for reflecting the electromagnetic waves from the radiator, wherein the reflector is provided at a first defined distance from the radiator, wherein the first defined distance corresponds to at least a thickness of an interior glass layer of the two glass layers disposed between the radiator and the reflector, and wherein the reflector comprises a first reflector layer and a second reflector layer arranged substantially in parallel and separated by a second defined distance.
An antenna system, comprising:
- an antenna embedded in a glass roof of a vehicle, wherein the antenna is substantially flat and is configured as a global navigation satellite system (GNSS) antenna, and wherein the antenna comprises:
- a radiator for radiating electromagnetic waves, wherein the radiator is:
- disposed between two glass layers of the glass roof,
- configured for feeding a signal to a receiver, and
- configured for radiating the electromagnetic waves in at least three frequency bands of GNSS;
- and
- a reflector for reflecting the electromagnetic waves from the radiator, wherein the reflector is provided at a first defined distance from the radiator, wherein the first defined distance corresponds to at least a thickness of an interior glass layer of the two glass layers disposed between the radiator and the reflector, and wherein the reflector comprises a first reflector layer and a second reflector layer arranged substantially in parallel and separated by a second defined distance.
A glass roof of a vehicle, comprising:
- an antenna embedded within the glass roof of the vehicle, wherein the antenna is substantially flat and is configured as a global navigation satellite system (GNSS) antenna, and wherein the antenna comprises:
- a radiator for radiating electromagnetic waves, wherein the radiator is:
- disposed between two glass layers of the glass roof,
- configured for feeding a signal to a receiver, and
- configured for radiating the electromagnetic waves in at least three frequency bands of GNSS;
- and
- a reflector for reflecting the electromagnetic waves from the radiator, wherein the reflector is provided at a first defined distance from the radiator, wherein the first defined distance corresponds to at least a thickness of an interior glass layer of the two glass layers disposed between the radiator and the reflector, and wherein the reflector comprises a first reflector layer and a second reflector layer arranged substantially in parallel and separated by a second defined distance.
