Abstract

The invention provides a small dielectric antenna having good mountability and unlikely to deteriorate its performance. The dielectric antenna includes feeder terminals (3, 4) attached to the lower surface or a side of a flat dielectric material (1). A striplike antenna electrode (2) is formed on the upper surface of the dielectric material (1). The feeder terminals (3, 4) and the antenna electrode (2) are connected within or through the side of the dielectric material. The dielectric material (1) is formed of ceramic, and the striplike antenna electrode (2) is formed in a spiral.
