Abstract
A patch antenna includes: a radiating element having a flat-plate shape; and a parasitic element provided at a position spaced away from the radiating element in planar view in which the radiating element is seen from a direction perpendicular to a plate surface of the radiating element. A longitudinal direction of the parasitic element is oriented along a direction of a line segment connecting a center of the radiating element and a feeding point in the planar view.
Claims20
A patch antenna comprising:
- an antenna main body having a dielectric body, a radiating element having a flat-plate shape provided on a first surface of the dielectric body, and a ground plate provided on a second surface of the dielectric body opposite to the first surface of the dielectric body in a first direction perpendicular to a plate surface of the radiating element;
- a parasitic element provided at a position on the first surface of the dielectric body and spaced away from the radiating element in planar view in which the radiating element is seen from the first direction;
- and
- a protrusion that extends along the first direction,
- wherein the antenna main body has a first outer surface closer to the radiating element than to the ground plate and a second outer surface opposite to the first outer surface along the first direction, the second outer surface being closer to the ground plate than to the radiating element, and
- wherein the protrusion is configured to directly contact the second outer surface of the antenna main body.
