Abstract
A communication device includes a transmitter (TX), a receiver (RX), one or more adaptively-tunable Electrically-Small Antennas (ESAs), and a control unit. The transmitter is configured to produce a TX signal for transmission on a TX frequency band. The receiver is configured to process an RX signal received on an RX frequency band. The adaptively-tunable ESAs are configured to transmit the TX signal on the TX frequency band and to receive the RX signal on the RX frequency band. The control unit is configured to adaptively tune respective responses of the one or more ESAs in the TX or RX frequency band.
Claims18
A communication device, comprising:
- a transmitter (TX), which is configured to produce a TX signal for transmission on a TX frequency band;
- a receiver (RX), which is configured to process an RX signal received on an RX frequency band that is different from the TX frequency band;
- an adaptively-tunable Transmit/Receive (TX/RX) Electrically-Small Antenna (ESA), configured to transmit the TX signal on the TX frequency band and to receive the RX signal on the RX frequency band;
- an adaptively-tunable Receive-only (RX) ESA, configured to receive the RX signal on the RX frequency band;
- and
- a control unit, which is configured to:
- adaptively tune a narrowband response of the TX/RX ESA to the TX frequency band, both while transmitting on the TX band and while receiving on the RX band, such that the TX/RX ESA has degraded reception performance relative to the RX ESA in the RX band;
- and
- while receiving on the RX band, to apply diversity reception to the RX signal received by the TX/RX ESA and the RX-only ESA, and to reduce an impact of the degraded reception performance of the TX/RX ESA by assigning the RX ESA to serve as a primary antenna and assigning the TX/RX ESA to serve as a secondary antenna.
A method for communication, comprising:
- transmitting a transmit (TX) signal on a TX frequency band via an adaptively-tunable Transmit/Receive (TX/RX) Electrically-Small Antenna (ESA), and receiving a receive (RX) signal on an RX frequency band, different from the TX frequency band, via the adaptively-tunable TX/RX ESA and via an adaptively-tunable Receive-only (RX) ESA;
- adaptively tuning a narrowband response of the TX/RX ESA to the TX frequency band, both while transmitting on the TX band and while receiving on the RX band, such that the TX/RX ESA has degraded reception performance relative to the RX ESA in the RX band;
- and
- while receiving on the RX band, applying diversity reception to the RX signal received by the TX/RX ESA and the RX-only ESA, and reducing an impact of the degraded reception performance of the TX/RX ESA by assigning the RX ESA to serve as a primary antenna and assigning the TX/RX ESA to serve as a secondary antenna.
