A three-axis antenna containing: a bobbin for housing a core, made of a resin having an top flange and a bottom flange both of which include four flange pieces at both ends of the winding column in the thickness direction of the core; a first coil and a second coil wound in the spaces between the flange pieces to cross each other at the upper and lower surfaces of the core; and a third coil wound at the side surface of the core and between the top flange and the bottom flange.

Three-axis antenna

A miniature surface-mount electronic component which can ensure sufficient impact resistance and vibration resistance especially in an application to a severe use environment such as a vehicle-mounted coil, by putting some contrivance into a method for fixing a coil in a molding process and a method for holding a core and terminals. A miniature surface-mount electronic component including a bar-shaped coreon which a winding wireis wound, and metal plates, with an outer casingmade of an insulating resin molded, includes flangessubstantially quadrangular in section at both ends of the bar-shaped core, and vertical grooves a and b are provided on side surfaces of the flangesof the bar-shaped coreas fixing portions for preventing positional displacement occurring when the outer casingis molded.

A triaxial antenna coil prevents wires from snapping, increases productivity, is resilient against dropping, and is suitable for being made small and light. A triaxial antenna coil includes coils, that are wound around three intersecting winding axes, and a flat core having winding grooves in three intersecting axial directions. A base has a terminal element, that is fitted with a plurality of external connectors and terminal connectors of windings. The base is fixed to one face of the core. The coils are wound in respective winding grooves, and their terminals are connected to the terminal connectors of the terminal element.
