Abstract
A glass antenna placed in a window glass for a vehicle includes a second antenna that includes a second power feeding point, and a second element connected to the second power feeding point; a third antenna that includes a third power feeding point, and a third element connected to a third power feeding point; and a no-power-fed element that includes a first overlapping part placed in parallel with at least a part of the second element, separated by a third interval, and a second overlapping part placed in parallel with at least a part of the third element, separated by a fourth interval.
Claims11
A glass antenna placed in a window glass for a vehicle, comprising:
- a first antenna that includes a first power feeding point, and a first element connected to the first power feeding point;
- a second antenna that includes a second power feeding point, and a second element connected to the second power feeding point;
- and
- a no-power-fed element into which no current flows, and which includes
- a first overlapping part extending in a same first direction as at least a part of the first element and placed in parallel with the at least a part of the first element, the first part being adjacent to the at least a part of the first element in a direction perpendicular to the first direction, and being separated from the at least a part of the first element by a first interval, and
- a second overlapping part extending in a same second direction as at least a part of the second element and placed in parallel with the at least a part of the second element, the second part being adjacent to the at least a part of the second element in a direction perpendicular to the second direction, and being separated from the at least a part of the second element by a second interval.
A window glass for a vehicle, comprising:
- a glass;
- a glass antenna installed in the glass, the glass antenna comprising:
- a first antenna that includes a first power feeding point, and a first element connected to the first power feeding point;
- a second antenna that includes a second power feeding point, and a second element connected to the second power feeding point;
- and
- a no-power-fed element that includes:
- a first overlapping part placed in parallel with at least a part of the first element, separated by a first interval, and
- a second overlapping part placed in parallel with at least a part of the second element, separated by a second interval;
- and
- a defogger that includes a plurality of first wires placed at equal intervals each being a third interval and extended in a first direction, and a defogger element connected to the first wires,
- wherein the glass includes a transparent area and a shading area provided around the transparent area,
- wherein the glass antenna includes a third power feeding point provided in the shading area, and a third element connected to the third power feeding point,
- wherein the defogger element includes a first part that is provided in the transparent area and is extended in the first direction, and a second part that is provided in the shading area and is connected to the first part,
- wherein the third element includes a third part that is provided in the transparent area and is extended in the first direction, and a fourth part that is provided in the shading area and is connected to the third part and the third power feeding point, and
- wherein a part of the second part and a part of the fourth part are placed to have an interval narrower than the third interval.
