Abstract
One aspect of the present invention is generally directed towards a system and method of tuning a transducer for transmitting and receiving a wireless signal. In an illustrative embodiment, a single transducer is coupled to a first or second circuit for either transmitting or receiving, respectively. Generally, electrical characteristics of the first circuit are adjusted to increase a magnetic field generated by the transducer. Conversely, electrical characteristics of the second circuit are adjusted to increase a signal generated by the transducer for receiving a magnetic field. Accordingly, a single transducer device can be tuned for either transmitting or receiving a corresponding wireless signal.

A method for supporting inductive communication, the method comprising the steps of:
- coupling a transducer to a selected first or second circuit for either transmitting or receiving;
- adjusting electrical characteristics of the first circuit to increase a magnetic field generated by the transducer;
- adjusting electrical characteristics of the second circuit to increase a signal generated by the transducer.
A method for supporting communication, the method comprising the steps of:
- switching to select either transmitting or receiving over a transducer;
- via a first circuit, effectively tuning the transducer to be a low impedance device for generating a magnetic field when a transmitter is switched to transmit over the transducer;
- via a second circuit, effectively tuning the transducer to be a high impedance device for receiving a magnetic field when a receiver is switched to receive over the transducer.
A method for supporting communication comprising the steps of:
- switching to select one of multiple circuit paths for either transmitting or receiving over a transducer via inductive coupling;
- reducing an overall impedance of a first circuit path including the transducer to transmit an inductive signal over the transducer;
- and
- reducing an overall impedance of at least a portion of a second circuit path including a switch for receiving an inductive signal over the transducer.
A method for supporting communication comprising the steps of:
- coupling one of multiple transducers to a circuit to transmit or receive a magnetic field;
- and
- adjusting characteristics of the circuit depending on which of the multiple transducers is coupled to the circuit.
