Abstract
One embodiment relates to a circuit for efficient wireless communication. The circuit includes an antenna feed and a plurality of communication paths stemming from the antenna feed, where different communication paths are associated with different frequency bands. The circuit also includes a shunt coupled to the antenna feed and adapted to selectively divert power from the antenna feed as a function of shunt control signal. Other methods and systems are also disclosed.
Claims24
A circuit for efficient wireless communication, comprising:
- an antenna feed;
- a plurality of communication paths stemming from the antenna feed, where different communication paths are associated with different frequency bands;
- and
- a shunt coupled to the antenna feed and adapted to selectively divert power from the antenna feed as a function of shunt control signal.
A radio frequency (RF) communication device, comprising:
- an antenna adapted to be coupled to a transmission feed and a reception feed;
- a plurality of transmission paths stemming from the transmission feed, where different transmission paths are associated with different transmission frequency bands;
- a plurality of reception paths stemming from the reception feed, where different reception paths are associated with different reception frequency bands;
- and
- a reception shunt coupled to the reception feed and adapted to selectively divert power from the reception feed during a transmission time slot when data is to be transmitted over the antenna.
A method for efficient wireless communication, comprising:
- transmitting a radio frequency transmission signal over a transmission feed of an antenna during a transmission time slot;
- and
- shunting power from a reception feed of the antenna during the transmission time slot.
A method for efficient wireless communication over an antenna associated with at least one transmission feed and at least one reception feed, comprising:
- identifying a reception time slot within a frame;
- during the reception time slot, receiving over the antenna a reception signal that includes frequency components of a first reception frequency band and a second frequency band;
- and
- providing the reception signal along the reception feed and concurrently shunting power from the transmission feed.
A radio frequency (RF) communication device, comprising:
- an antenna adapted to be coupled to a transmission feed and a reception feed;
- means for selectively diverting power from the transmission feed during a reception time slot in which a reception radio frequency signal is to be received over the reception feed;
- and
- means for selectively diverting power from the reception feed during a transmission time slot in which a transmission radio frequency signal is to be transmitted over the transmission feed.
