Abstract: A magnetoresistive effect device includes a magnetoresistive effect element first and second ports, a signal line, an inductor, and a direct current input terminal. The first port, the magnetoresistive effect element, and the second port are connected in series in this order via the signal line. The inductor is connected to one of the signal line between the magnetoresistive effect element and the first port and the signal line between the magnetoresistive effect element and the second port and is capable of being connected to ground. The direct-current input terminal is connected to the other of the above signal lines. A closed circuit including the magnetoresistive effect element, the signal line, the inductor, the ground, and direct-current input terminal is capable of being formed. The magnetoresistive effect element is arranged so that direct current flows in a direction from a magnetization fixed layer to a magnetization free layer.

Abstract: A magnetoresistive effect device includes a magnetoresistive effect element including a magnetization fixed layer, a spacer layer, and a magnetization free layer; a first port; a second port; a signal line; an impedance element; and a direct-current input terminal. The first port, the magnetoresistive effect element, and the second port are connected in series in this order via the signal line. The impedance element is connected to ground and to the signal line between the magnetoresistive effect element and the first port or the second port. The direct-current input terminal is connected to the signal line at the opposite side to the impedance element with the magnetoresistive effect element in between the direct-current input terminal and the impedance element. A closed circuit including the magnetoresistive effect element, the signal line, the impedance element, the ground, and the direct-current input terminal is to be formed.

Abstract: The present invention is to provide an antenna device with the isolation among feedpoints being further improved. In order to achieve this goal, the present invention provides an antenna device provided with a substrate having a ground area, and a first conductor, a second conductor and a third conductor. In the antenna, one end of the second conductor is connected to the ground area via a first feedpoint and the other end of the second conductor is connected to the first conductor. A second feedpoint is included serially in the third conductor at any position. Further, at least part of the third conductor is disposed opposite to the first conductor, and both ends of the third conductor are connected to the ground area.
