ANTENNA
An antenna includes an antenna element having a belt-shaped tip of which edge is chamfered at two corners, and the belt-shaped tip has a rectangular stopper hole at its width center. The antenna includes a base on which a pedestal is formed corresponding to the belt-shaped tip. The pedestal is provided with an arched protrusion shaped like letter “U” so that an insertion slit slightly greater than the belt-shaped tip in width and thickness can be formed. A stopper protrusion is formed on an inner wall of the arched protrusion such that it corresponds to the stopper hole. The belt-shaped tip is inserted into the slit with ease, and the stopper hole mates with the stopper protrusion, thereby fixing the antenna element to the base in a simple manner.
1 . An antenna comprising:
an antenna element made of thin metal sheet; and
a base made of resin having a first face and a second face confronting each other;
wherein the antenna element is disposed in a continuous form on the first face and the second face of the base,
wherein the antenna element disposed on the first face has an end of which tip is shaped like a belt and has a stopper hole near an edge of the tip,
wherein the belt-shaped tip is disposed on the second face of the base, and the second face includes an arched protrusion having an insertion slit into which the belt-shaped tip can be inserted along a direction parallel to a surface of the second face, and the insertion slit has a riveting protrusion on an inner wall of the slit, and the stopper protrusion mates with the stopper hole of the antenna element, and
wherein when the belt-shaped tip is inserted into the slit, the stopper protrusion mates with the stopper hole for fixing the belt-shaped tip to the base.
