CHIP ANTENNA
Document Type and Number:
Japanese Patent JP3166589
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a small-sized chip antenna having plural resonance frequencies used for applications such as mobile communication.
SOLUTION: This chip antenna 10 is provided with a rectangular parallelepiped base body 11 made of a dielectric material (specific dielectric constant: nearly 6.1) composed substantially of barium oxide, aluminum oxide and silica, conductors 12a, 12b made of a copper or a copper alloy provided in the interior of the base body 11 and wound in spiral in the lengthwise direction of the base body 11, and a feeding terminal 15 provided to a side face and a lower face of the base body 11 to apply a voltage to the conductors 12a, 12b. In this case, the conductors 12a, 12b are connected in series by a via hole 14, one end of the conductor 12a forms a feeding section 16 connecting to a feeding terminal 15 and the other end of the conductor 12b forms an open free end 17 in the interior of the base body 11.
