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.
Claims30
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;
- and
- 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.
