To provide a loop antenna device which inhibits the unnecessary radiation of the electric wave and which can increase the sending speed of data placed on the electric wave. The first loop antenna includes the coil L and the resonant capacitor C and constitutes a series resonant circuit in which the oscillator is connected in series to the coil L and the resonant capacitor C The second loop antenna includes the coil L and the resonant capacitor C which are connected each other in parallel and constitutes a parallel resonant circuit. The second loop antenna is magnetically connected to the first loop antenna via the link coil L The switching elements are connected to the first and second loop antennas and the damping is performed to the resonant circuits of the antennas when the switching elements become OFF condition by the control signal from the controller
