Abstract
A glass antenna is installed on a glass having a first edge and a second edge opposite the first edge. A first antenna element extends linearly in a direction from the first edge to the second edge of the glass. A second antenna element extends in a direction opposite to the direction of the first antenna and is connected to a grounding point provided on the first edge of the glass. At least one third antenna element extends along the circumference of the glass and intersects one of a tip of the first antenna element and a base of the second antenna element.
Claims16
A glass antenna installed on a glass configured for attachment to an opening portion of a vehicle body, the glass having a first edge and a second edge opposite the first edge, the glass antenna comprising:
- a first antenna element extending linearly from a feed point provided at the first edge of the glass toward the second edge of the glass;
- a second antenna element folded and connected to a distal end of the first antenna element, the second antenna element extending in a direction opposite to a direction of extension of the first antenna element, the second antenna element being connected to a ground point provided at the first edge of the glass;
- and
- a pair of third antenna elements extending along the opening portion of the vehicle body to a distal end of the first antenna element and a proximal end of the second antenna element, respectively.
A glass antenna installed on a glass having a first edge and a second edge opposite the first edge, the glass antenna comprising:
- a first antenna element extending linearly in a direction from the first edge to the second edge of the glass;
- a second antenna element extending in a direction opposite to the direction of the first antenna and connected to a grounding point provided on the first edge of the glass;
- and
- a pair of third antenna elements intersecting a tip of the first antenna element and a base of the second antenna element, respectively, and extending along a circumference of the glass;
- wherein the first antenna element extends linearly from a feed point provided at the first edge of the glass;
- wherein at least one of the pair of third antenna elements has a first antenna section extending away from the second antenna element and a second antenna section extending away from the first antenna element;
- and further comprising a first bypass antenna element branching off from an end portion of the first antenna section and extending to the feed point, and a second bypass antenna element branching off from an end portion of the second antenna section and extending to the ground point.
In combination with a glass mounted to an opening portion of a vehicle body, a glass antenna comprising:
- a first antenna element extending linearly from a feed point provided at a first edge of the glass toward a second edge of the glass opposite the first edge;
- a second antenna element connected to a distal end of the first antenna element and connected to a ground point provided at the first edge of the glass and connected to the vehicle body;
- and
- a pair of third antenna elements extending along the opening portion of the vehicle body and to the distal end of the first antenna element and a proximal end of the second antenna element, respectively.
