ABSTRACT:
A rectangular-prism-shaped base member is made from a dielectric material or a magnetic material. A ground electrode and a power supplying electrode are formed on one end face of the base member with a gap disposed therebetween. At least one through hole is formed between the end face and the opposing end face. A radiation electrode is formed on the inside surface of the through hole. One end of the radiation electrode is connected to the ground electrode, and the other end serves as an open end. The power supplying electrode and the radiation electrode are electromagnetically coupled through a capacitor formed at the gap.
