Chip antenna

摘要

A chip antenna (10;20) in which correct evaluation and inspection of a conductor (12;22) can be performed regardless of the state of grounding. The chip antenna (10;20) has a rectangular-prism-shaped substrate (11;21) formed of a dielectric material comprising, e.g., barium oxide, aluminum oxide and silica. A copper or copper-alloy conductor (12;22) is spirally wound within the substrate (11;21) in the longitudinal direction. A feeding terminal (16) for applying a voltage to the conductor (12;22) and a free terminal (17) are disposed on the surfaces of the substrate (11;21). One end (12a;22a) of the conductor (12;22) is attached to the feeding terminal (16), while the other end (12b;22b) is connected to the free terminal (17). <IMAGE> <IMAGE>
