Abstract
This multi-antenna apparatus includes a first looped antenna element wound from a first end of the first looped antenna element on a side of a first feeding point in a prescribed direction, a second looped antenna element wound from a first end of the second looped antenna element on a side of a second feeding point in a direction opposite to the prescribed direction, a connecting portion connecting a second end of the first looped antenna element and a second end of the second looped antenna element with each other, and an impedance element arranged between the connecting portion and a ground potential.
Claims18
A multi-antenna apparatus comprising:
- a first looped antenna element wound from a first feeding point in a prescribed direction;
- a second looped antenna element wound from a second feeding point in a direction opposite to said prescribed direction;
- a connecting portion connecting a vicinity of an end of said first looped antenna element on a side opposite to a side on which said first feeding point is arranged and a vicinity of an end of said second looped antenna element on a side opposite to a side on which said second feeding point is arranged;
- and
- an impedance element arranged between said connecting portion and a ground potential, wherein
- a voltage in a direction to cancel a voltage induced in said second looped antenna element due to a current flowing in said first looped antenna element is generated by a current flowing in said ground potential through said impedance element when the current flows in said first looped antenna element at a prescribed frequency.
A mobile device comprising a multi-antenna apparatus including:
- a first looped antenna element wounded from a first feeding point in a prescribed direction;
- a second looped antenna element wound from a second feeding point in a direction opposite to said prescribed direction;
- a connecting portion connecting a vicinity of an end of said first looped antenna element on a side opposite to a side on which said first feeding point is arranged and a vicinity of an end of said second looped antenna element on a side opposite to a side on which said second feeding point is arranged;
- and
- an impedance element arranged between said connecting portion and a ground potential, wherein
- a voltage in a direction to cancel a voltage induced in said second looped antenna element due to a current flowing in said first looped antenna element is generated by a current flowing in said ground potential through said impedance element when the current flows in said first looped antenna element at a prescribed frequency.
