Chip antenna and method of manufacturing the same

A method of manufacturing a chip antenna whose antenna element has a capacitance-adding portion at a distal end of a line antenna portion and is buried in a resin molding having a predetermined chip shape, comprising the step of:

• sandwiching frame portions at both sides of said antenna element between an upper die and a lower die of a mold for injection molding, positioning said line antenna portion and said capacitance-adding portion in a cavity of said mold and then injecting a dielectric into said cavity from outward of said capacitance-adding portion as seen from a center of said antenna element.

A method of manufacturing a chip antenna which has an antenna element buried in a resin molding having a predetermined chip shape and terminal portions provided continuously to said antenna element and protruding from said resin molding, comprising the steps of:

• sandwiching portions of said terminal portions between an upper die and a lower die of a mold for injection molding, and positioning a line antenna portion in a cavity of said mold and then injecting a dielectric into said cavity to bury said antenna element, wherein said upper die and said lower die of said mold for injection molding sandwich a conductive pattern, thereby forming a cavity having a shape of an approximately rectangular parallelepiped, and said upper die and said lower die are shaped to have portions protruding into said cavity and sandwiching said terminal portions of said conductive pattern.
