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.
