Abstract
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.
Claims13
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.
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.
