Patent ID: 8521240

Claim:
A mobile terminal device, comprising: a first body; a second body; a first conductive portion disposed in the first body and including a first contact point; a second conductive portion disposed in the second body and including a second contact point; and a first circuit unit disposed in any one of the first body and the second body, the first circuit unit including: a first ground unit connected to the first conductive portion via the first contact point; a first power supply unit connected to the second conductive portion via the second contact point; and a first signal processing unit connected to the first power supply unit, configured to process a first high frequency signal resonated by the second conductive portion, wherein the first conductive portion includes a first area overlapping with the second conductive portion, wherein the second conductive portion includes a second area overlapping with the first conductive portion, wherein a first cutoff part is connected to at least one of the first conductive portion and the second conductive portion, and cuts off transmission of the first high frequency signal to an area toward a first end side from the first contact point of the first area, or to an area toward a second end side from the second contact point of the second area, wherein a second cutoff part is connected to at least one of the first conductive portion and the second conductive portion, and cuts off transmission of the second high frequency signal to an area toward the second end side from the first contact point of the first area, or to an area toward the first end side from the second contact point of the second area, and the second cutoff part is an electronic component that cuts off transmission of the first high frequency signal and allows a direct current signal to pass therethrough.
