Wireless Terminals Including Smart Antenna Systems Having Multiple Antennas
First Claim
1. A wireless communication device, comprising:
- a transceiver configured for communication using multiple communication modes, the transceiver comprising a transmitter and a receiver;
a plurality of antennas coupled to the transceiver, the plurality of antennas including a first antenna and a second antenna, wherein the multiple communication modes include a multiple input multiple output (“
MIMO”
) mode and a single antenna receive mode; and
a control circuit configured to detect selection of the single antenna receive mode as an active one of the multiple communication modes and to automatically alter a configuration of the plurality of antennas and transceiver by configuring the first antenna as a transmit only antenna and the second antenna as a receive only antenna responsive to detection of the selection of the single antenna receive mode.

Abstract
A wireless communication device includes a transceiver configured for communication using multiple communication modes, the transceiver comprising a transmitter and a receiver. A plurality of antennas is coupled to the transceiver. The plurality of antennas includes a first antenna and a second antenna. The multiple communication modes include a multiple input multiple output (“MIMO”) mode and a single antenna receive mode. The device further includes a control circuit configured to detect selection of the single antenna receive mode as an active one of the multiple communication modes and to automatically alter a configuration of the plurality of antennas and transceiver by configuring the first antenna as a transmit only antenna and the second antenna as a receive only antenna responsive to detection of the selection of the single antenna receive mode. Related methods of operation are also discussed.
