CHIP ANTENNA AND ANTENNA DEVICE

摘要

Provided is a chip antenna which is not easily affected by a ground electrode existing below the chip antenna in the state where the chip antenna is mounted on a circuit substrate, has less frequency fluctuation and less deterioration of antenna gain.  An antenna device provided with the chip antenna is also provided. A non power feeding electrode (18) is formed over the fourth side surface of a dielectric base body (10) to the upper surface thereof.  Another non power feeding electrode (12) is formed over the third side surface of the dielectric base body (10) to the upper surface thereof.  The leading end of the non power feeding electrode (18) and that of the non power feeding electrode (12) face each other with a predetermined space therebetween on the upper surface of the dielectric base body (10).  On the lower surface of the dielectric base body (10), non power feeding electrode lower surface electrodes (18C, 12C) electrically connected to the non power feeding electrodes (18, 12) are formed.  On the lower surface of the dielectric base body (10), a power feeding electrode lower surface electrode (19C) electrically connected to a power feeding electrode (19) is formed.
