Abstract: A vehicular antenna device (10) includes an antenna base (100) and a first antenna portion (a first satellite antenna (210) or a second satellite antenna (220)). The antenna base (100) has a longitudinal direction. The first antenna portion is provided over the antenna base (100). The satellite antennas are disposed offset in a direction intersecting a virtual plane parallel or substantially parallel with the longitudinal direction.

Abstract: An antenna apparatus has a sleeve antenna. The sleeve antenna has an internal conductive member, an external conductive member, an insulating member, and a mountain-shaped conductive member that is electrically connected to the external conductive member. The mountain-shaped conductive member expands radially from an upper edge towards a lower edge. The internal conductive member protrudes higher than the external conductive member above the upper edge of the mountain-shaped conductive member.
