Abstract
An antenna includes a cylindrical substrate, an arc-shaped outer metal strip formed on an outer surface of the cylindrical substrate, and an arc-shaped inner metal strip formed on an inner surface of the cylindrical substrate. A cross section of the cylindrical substrate forms a complete circle with a center angle equal to 360 degrees or forms an arc with a center angle less than 360 degrees. The cylindrical substrate, the arc-shaped outer metal strip, and the arc-shaped inner metal strip have a common central axis.
