1. An antenna comprising:
a dielectric layer including a first main surface and a second main surface opposite to the first main surface;
a conductive ground layer formed on the first main surface;
a first radiation element that is formed on the second main surface and is conductive; and
a second radiation element that is formed side by side with the first radiation element on the second main surface and is conductive, wherein
the first radiation element includes a first non-uniform width part having a width in a direction parallel to a first side in a linear shape opposed to a first vertex part, the width of the first non-uniform width part gradually decreasing in a direction from the first side to the first vertex part, and
the second radiation element includes a second non-uniform width part having a width in a direction parallel to a second side in a linear shape opposed to a second vertex part, the width of the second non-uniform width part gradually decreasing in a direction from the second side to the second vertex part,
wherein
the first non-uniform width part includes the first vertex part,
the first radiation element includes a first uniform width part continuous from the first non-uniform width part toward the first side,
the first uniform width part includes the first side, and a width of the first uniform width part is uniform in the direction parallel to the first side,
the second non-uniform width part includes the second vertex part,
the second radiation element includes a second uniform width part continuous from the second non-uniform width part toward the second side, and
the second uniform width part includes the second side, and a width of the second uniform width part is uniform in the direction parallel to the second side.
