1. An inductor circuit, comprising:
a receiver inductive circuit;
a transmitter inductive circuit, being respectively coupled to and used by a transmitter circuit and a receiver circuit during different time periods; and
an antenna inductive circuit, having a first end coupled to a first signal port of an antenna circuit and a second end coupled to a second signal port of the antenna circuit;
wherein the receiver inductive circuit is disposed on a specific ring of a specific plane to form a ring shape; the transmitter inductive circuit and the antenna inductive circuit are disposed inside the specific ring and surrounded by the specific ring of the specific plane; and, a circuit area, occupied by the transmitter inductive circuit, inside the specific ring and on the specific plane, is larger than a circuit area occupied by the receiver inductive circuit and by the antenna inductive circuit.
