Abstract
A lens antenna array system for wireless communication is provided that includes a lens antenna array transmitter having a first lens and a lens antenna array receiver having a second lens. The lens antenna array transmitter transmits a plurality of RF signals across a plurality of near-field communication links to the lens antenna array receiver.
Claims29
A lens antenna array system, comprising:
- a first lens;
- a plurality of transmit antennas arranged in a focal region of the first lens;
- a second lens;
- and
- a plurality of receive antennas arranged in a focal region of the second lens, the first lens being aligned with the second lens so that a plurality of transmitted RF signals propagates from the first lens to the second lens in a near-field regime.
2 more elements
A method of wireless communication, comprising:
- modulating a first RF signal responsive to a first input data stream to form a first modulated RF signal;
- driving the first modulated RF signal through a first transmit antenna at a first location within a focal region of a first lens to transmit the first modulated RF signal from the first lens;
- propagating the first modulated RF signal across a near-field separation between the first lens and a second lens, the first modulated RF signal arriving with a first angle-of-arrival at the second lens;
- and
- focusing the first modulated RF signal through the second lens responsive to the first angle-of-arrival to concentrate the first modulated RF signal on a first receive antenna at a first location within a focal region of the second lens.
2 more elements
A method of wireless communication, comprising:
- for a plurality of transmit antennas arranged in a focal region of a first lens so that each transmit antenna maps to a corresponding angle of departure;
- transmitting an RF signal from each transmit antenna to propagate the RF signal in a near-field regime from the first lens according to the transmit antenna's corresponding angle of departure to arrive at a second lens at a corresponding angle of arrival;
- and
- focusing each RF signal through the second lens responsive to the RF signal's corresponding angle of arrival so that each RF signal is focused onto a respective receive antenna from a plurality of receive antennas arranged in a focal region of the second lens.
1 more element
A lens antenna array system, comprising:
- a first processor configured to provide a plurality of baseband input data streams;
- a plurality of modulators corresponding to the plurality of baseband input data streams, each modulator in the plurality of modulators configured to modulate a respective baseband input data stream from the plurality of baseband input data streams to produce a modulated RF signal;
- a plurality of power amplifiers corresponding to the plurality of modulators, each power amplifier configured to amplify a respective modulator's modulated RF signal according to a gain to produce an amplified modulated RF signal;
- a first lens;
- a plurality of transmit antennas corresponding to the plurality of power amplifiers, each transmit antenna in the plurality of transmit antennas being configured to transmit the amplified modulated RF signal from a respective power amplifier, the plurality of transmit antennas being arranged in a focal region of the first lens
- a second lens;
- and
- a plurality of receive antennas arranged in a focal region of the second lens, the first lens being aligned with the second lens so that each amplified modulated RF signal propagates from the first lens to the second lens in a near-field regime.
