Abstract
An antenna apparatus includes: a ground plane including first sides parallel to a first direction and second sides parallel to a second direction, on a plane formed in the first and second directions; a dielectric layer disposed on the ground plane in a third direction; an antenna patch overlapping the ground plane in the third direction; and vias connected to the ground plane and passing through at least a portion of the dielectric layer. Edges of the vias at least partially overlap the first sides of the ground plane in the third direction.
Claims20
An antenna apparatus, comprising:
- a ground plane including first sides parallel to a first direction and second sides parallel to a second direction, on a plane formed in the first direction and the second direction;
- a dielectric layer disposed on the ground plane in a third direction;
- an antenna patch overlapping the ground plane in the third direction;
- and
- vias connected to the ground plane and configured to pass through at least a portion of the dielectric layer,
- wherein edges of the vias at least partially overlap the first sides of the ground plane in a top view of the plane formed in the first direction and the second direction, and
- wherein a length of each of the first sides in the first direction is greater than a length of each of the second sides in the second direction.
An antenna apparatus, comprising:
- a ground plane including first sides parallel to a first direction and second sides parallel to a second direction, on a plane formed in the first direction and the second direction;
- a dielectric layer overlapping the ground plane in a third direction;
- an antenna patch overlapping the ground plane in the third direction;
- a plurality of first vias configured to pass through at least a portion of the dielectric layer and connected to the ground plane;
- and
- a plurality of second vias disposed to be spaced apart from the plurality of first vias in the first direction,
- wherein a first distance between the plurality of first vias and the plurality of second vias in a direction parallel to the first direction is not greater than a minimum distance between the plurality of second vias and the antenna patch in the direction parallel to the first direction,
- wherein edges of the first vias and the second vias at least partially overlap the first sides of the ground plane in a top view of the plane formed in the first and second directions,
- wherein the dielectric layer includes a first edge parallel to the first direction and a second edge parallel to the second direction, and
- wherein a length of each of the first sides in the first direction is longer than a length of each of the second sides in the second direction.
