A disclosed antenna apparatus includes a base made of a dielectric material; an antenna element pattern formed on a surface of the base; a ground pattern formed in a position adjacent to and opposite to the antenna element pattern on the same surface of the base; and a surface-mounted coaxial connector mounted on the ground pattern in a position close to a feeding point of the antenna element pattern.
摘要:
An antenna apparatus is disclosed that includes a dielectric substrate, an antenna element pattern that is formed on an upper face of the dielectric substrate, a strip line that is formed on the upper face of the dielectric substrate and extends from the antenna element pattern, and a ground pattern that is formed on the upper face of the dielectric substrate and is arranged on either side of the strip line. The strip line, the ground pattern, and the substrate form a coplanar microwave transmission line.
