Patent Images
1. A surface mount antenna comprising:
- a substrate;
a conductive portion disposed at least one of in and on a surface of said substrate;
an electrical supply terminal on a surface of said substrate for applying voltage to said conductive portion;
the conductive portion having one end coupled to the electrical supply terminal and a second end left unconnected;
a covering material covering at least a portion of said substrate; and
the substrate having at least one flat surface to be mounted on a mounting board;
wherein the substrate comprises a plurality of laminated layers with respective parts of the conductive portion on respective ones of the layers, via holes being provided on at least one of said layers as a portion of a part of the conductive portion on said at least one layer for interconnecting with at least one other part to form said conductive portion when said layers are placed together to form said substrate.

Abstract
A surface mount antenna having increased mechanical strength, and whose properties do not deteriorate when exposed to heat and moisture. The surface mount antenna includes a substrate, and a conductive portion in or on the substrate, with an electrical supply terminal formed on a surface of the substrate in order to apply voltage to the conductive portion. A covering material is provided to cover the substrate by coating, dipping, or the like.
