1. An antenna comprising:
- a triangle planar substrate;
a radiation element which is disposed on the triangle planar substrate so as to have a center on a bisector which bisects a vertex angle of the triangle planar substrate, and the center position different from a median point of the triangle planar substrate; and
a feeder portion configured to supply power to the radiation element.

Abstract
A patch having a circular shape for instance is formed on the main surface of a substrate in the shape of, for example, an equilateral triangle. The center of the main surface of the patch is at a position different from the center of the substrate. A grounding conductor is disposed on the backside of the substrate. Power is supplied to the patch through, for example, a microstrip line, triplate line, coplanar waveguide, slot line or the like. An antenna configured as described above has the center of the patch at a position different from the center of the triangle substrate, so that beams can be tilted in a desired direction by a single patch and a single feeder circuit.
