Surface-mount antenna and communication apparatus using same

摘要

A compact surface-mount antenna is constructed from a rectangular-prism-shaped base member made from a dielectric material or a magnetic material. A through-hole is formed between one end-face and the opposing end-face in the base member. A radiation electrode is formed on the inside surface of the through-hole. One end of the radiation electrode is connected to a ground electrode formed on the one end-face, and the other end of the radiation electrode serves as an open end on the opposite end-face. A power-supplying electrode is formed through a dielectric gap disposed around the open end on the opposite end-face.
