Luneburg lens signal repeater
Systems, methods, and computer-readable media are described herein which utilizes and controls an electromagnetic energy beam steering apparatus. The electromagnetic energy beam steering apparatus uses directional properties of a Luneburg lens to receive RF energy from one or more points of the Luneburg lens and re-transmits the RF energy from a different point of the Luneburg lens to focus the RF energy in a desired direction. The electromagnetic energy beam steering apparatus may take a form of a passive repeater, an active repeater, or a multipath active repeater.
1. An electromagnetic energy beam steering apparatus comprising:
a Luneburg lens;
a first receive antenna and a second receive antenna, wherein the first receive antenna is located at a first focal point of the Luneburg lens, and wherein the second receive antenna is located at a second focal point of the Luneburg lens, and wherein the first receive antenna is positioned to receive a first multipath signal and the second receive antenna is positioned to receive a second multipath signal; and
a transmission line, wherein the transmission line combines a first collected signal from the first receive antenna with a second collected signal from the second receive antenna to create a first combined signal; and
a first transmit antenna, wherein the first transmit antenna receives the first combined signal and transmits the first combined signal through the Luneburg lens.
2. The electromagnetic energy beam steering apparatus of claim 1 , wherein the first focal point and the second focal point are adjacent to each other.
3. The electromagnetic energy beam steering apparatus of claim 1 , wherein a location of the first focal point is optimized to receive a first signal.
4. The electromagnetic energy beam steering apparatus of claim 3 , wherein the first signal is transmitted from an RF transceiver.
5. The electromagnetic energy beam steering apparatus of claim 4 , wherein the RF transceiver is a base station comprising a radio and a Massive Multiple-Input Multiple-Output unit.
6. The electromagnetic energy beam steering apparatus of claim 3 , wherein a location of the second focal point is optimized to transmit the first signal to a desired location.
7. An electromagnetic energy beam steering method comprising:
receiving a first signal at a Luneburg lens, wherein the first signal comprises a communication signal transmitted using either a 4G or a 5G wireless access technology;
collecting a first collected signal from the Luneburg lens at a first antenna, wherein the first antenna is located at a first focal point of the Luneburg lens; and
transmitting the first collected signal through a transmission line system, wherein the transmission line system transmits the first collected signal from the first antenna and combines the first collected signal with a signal used to mitigate self-interference cancellation to create a first transmit signal which is then transmitted to a second antenna and transmitted through the Luneburg lens, wherein the second antenna is located at a second focal point of the Luneburg lens.
8. The electromagnetic energy beam steering method of claim 7 , wherein the first focal point and the second focal point are orthogonal to each other.
9. The electromagnetic energy beam steering method of claim 7 , wherein a location of the first focal point is optimized to receive the first signal.
10. The electromagnetic energy beam steering method of claim 9 , wherein the first signal is transmitted from an RF transceiver.
11. The electromagnetic energy beam steering method of claim 10 , wherein the RF transceiver is a small cell RF transceiver.
12. The electromagnetic energy beam steering method of claim 9 , wherein a location of the second focal point is optimized to transmit the first signal to a desired location.
13. The electromagnetic energy beam steering method of claim 7 , wherein the signal used to mitigate self-interference cancellation is generated using a copy of the first collected signal.
