Abstract
The antenna unit including a first antenna portion including a first element, a first board for mounting the first element, and a feeding conductor for electrically connecting the first element and the first board and capable of receiving a radio wave in a first frequency band, and a second antenna portion including a second element shorter than the first element, and a second board for mounting the second element and capable of receiving a radio wave of a second frequency band higher than the first frequency band, in which a length of a transmitting path of the feeding conductor and a length of the second element are formed to configure lengths different from each other.
Claims22
An antenna unit comprising:
- a first antenna portion capable of receiving a radio wave in a first frequency band, the first antenna portion including:
- a first element;
- a first board for mounting the first element;
- and
- a feeding conductor for electrically connecting the first element and the first board, and
- a second antenna portion capable of receiving a radio wave of a second frequency band higher than the first frequency band, the second antenna portion including:
- a second element shorter than the first element;
- and
- a second board for mounting the second element,
- wherein the first board and the second board are arranged on substantially the same plane with respect to each other, and
- wherein a length of a transmitting path of the feeding conductor and a length of the second element are configured to be different from each other.
An antenna unit comprising:
- a first antenna portion capable of receiving a radio wave of a first frequency band, the first antenna portion including a first element;
- a second antenna portion capable of receiving a radio wave of a second frequency band higher than the first frequency band, the second antenna portion including a second element shorter than the first element;
- and
- a board for mounting the first element and the second element,
- wherein the first antenna portion further includes a feeding conductor for electrically connecting the first element and the board, and
- the feeding conductor is configured such that a length of a transmitting path thereof differs from a length of the second element.
An antenna unit comprising:
- first means for receiving a radio wave of a first frequency band;
- second means for receiving a radio wave of a second frequency band higher than the first frequency band;
- means for connecting and supporting the first means and the second means thereto;
- and
- means for electrically connecting the first means to the means for connecting and supporting,
- wherein a length of a transmitting path of the means for electrically connecting is greater than a length of the second means.
An antenna unit comprising:
- a first antenna portion capable of receiving a radio wave in a first frequency band, the first antenna portion including:
- a first element;
- a first board for mounting the first element;
- and
- a feeding conductor comprising a meandering structure for electrically connecting the first element and the first board, and
- a second antenna portion capable of receiving a radio wave of a second frequency band higher than the first frequency band, the second antenna portion including:
- a second element shorter than the first element;
- and
- a second board for mounting the second element,
- wherein a length of a transmitting path of the feeding conductor and a length of the second element are configured to be different from each other.
An antenna unit comprising:
- a first antenna portion capable of receiving a radio wave in a first frequency band, the first antenna portion including:
- a first element;
- a first board for mounting the first element;
- and
- a feeding conductor comprising a slot structure for electrically connecting the first element and the first board, and
- a second antenna portion capable of receiving a radio wave of a second frequency band higher than the first frequency band, the second antenna portion including:
- a second element shorter than the first element;
- and
- a second board for mounting the second element,
- wherein a length of a transmitting path of the feeding conductor and a length of the second element are configured to be different from each other.
