Claim Text:
1. 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: 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.
