Insulated wire, coil, and electric or electronic equipment

A small antenna comprises an antenna conductor, and a dielectric chip formed at surroundings of the antenna conductor by a plurality of resin moldings.

Small antenna and manufacturing method thereof

A line-shaped comprises an antenna element in which a strip-shaped conductor is bent in a width direction of a strip, and a chamfered portion is provided on an outer edge of a bent portion of the strip-shaped conductor.

Line-shaped antenna

Of margins of a resin molding with an antenna element buried therein which lie around the antenna element, a margin on that side of the resin molding where a gate mark remains is made larger than margins on other sides where there is no gate mark. Particularly, when the antenna element has a line antenna portion and a capacitance-adding portion provided at a distal end of the line antenna portion, the resin molding is injection-molded in such a way that a gate mark can be formed on that side where the capacitance-adding portion is located. Those portions of the resin molding where the terminal portions are led out are dented from levels of portions around those portions. This provides a chip antenna which has a simple structure with a high mechanical strength and does not prevent separation or cracking from occurring in the resin molding in which the antenna element is buried and a method of manufacturing the chip antenna.

Chip antenna and method of manufacturing the same

An antenna apparatus comprises a substrate, a chip antenna mounted on the substrate, and a ground pattern disposed on the substrate, at least a portion on the side of a power supply terminal of an antenna conductor in the chip antenna being overlapped with the ground pattern.
