Abstract
A meander line antenna includes a rectangular-parallelopiped base member made from a dielectric material having barium oxide, aluminum oxide, and silica as main components, a meander-shaped conductor having, e.g., 10 corners made of copper or a copper alloy by printing, deposition, pasting, or plating inside the base member, and a power-feed terminal for applying a voltage to the conductor. The meander-shaped conductor is formed in the longitudinal direction of the base member. One end of the conductor is led to a surface of the base member to form a power-feed section and is connected to the power-feed terminal. The other end of the conductor serves as an open end inside the base member.
