Claim 0:
1. An antenna element comprising:
a dielectric substrate including a flat-plate-shaped first portion and a second portion thinner than the first portion;
a first ground electrode arranged in the first portion;
a second ground electrode arranged in the second portion;
a via conductor coupling the first ground electrode with the second ground electrode;
a first radiation electrode arranged so as to lie opposite to the first ground electrode in the first portion in a first thickness direction of the first portion and lie opposite to the second ground electrode in the second portion in a second thickness direction of the second portion; and
a second radiation electrode, wherein:
a distance between the first radiation electrode and the first ground electrode in the first thickness direction is more than a distance between the first radiation electrode and the second ground electrode in the second thickness direction,
a part of the first radiation electrode lies opposite to the first ground electrode without lying opposite to the second ground electrode,
the dielectric substrate is bent in the second portion, and
a normal direction of the first radiation electrode is different from a normal direction of the second radiation electrode.
