ABSTRACT:
An antenna apparatus includes an antenna, and a resin material provided between the antenna and a reflector (windshield). The resin material includes portions, and the thickness (or dielectric constant) of each portion of the resin material is determined in accordance with a length of a straight line connecting a feeding point of the antenna, each portion of the resin material, and the reflector. Therefore, a phase of a reflected wave can be easily adjusted, thereby improving a performance of the antenna.
