Claim Text:
1. A patch antenna comprising: a dielectric body which increases in cross-sectional area from a first end toward a second end thereof; a radiation element which is disposed on a surface of the dielectric body and each side of which has a length adjusted based on a frequency of a radio wave to be received and an effective permittivity of the dielectric body; an earth conductor disposed on a bottom surface of the dielectric body; and a feed member electrically connected to the radiation element, wherein the dielectric body has an inclined plane which is inclined so that the dielectric body increases in height along a to surface thereof from the first end toward the second end thereof, and wherein the dielectric body decreases in width from the first end toward the second end thereof so as to have a shape of a trapezoid when viewed from above.
