<P>PROBLEM TO BE SOLVED: To provide an antenna which is made compact while minimizing deterioration of performance. <P>SOLUTION: The antenna 1 includes a substrate 11 and an element member 12. On the surface A of the substrate 11, a ground pattern 111 and a feed pattern 112 consisting of a conductor pattern are provided. The element member 12 consists of a bent sheet plate and is disposed on the substrate 11. The element member 12 includes a rising part 121, a parallel part 122, and a return part 123. The rising part 121 is rising from the feed pattern 112 for the substrate 11. The parallel part 122 is bent from the tip of the rising part 121, and extends in parallel with the surface A while facing the plate surface toward the surface of the substrate 11. The return part 123 is bent from the parallel part 122 and returns back to the surface A of the substrate 11. The substrate 11 is provided, on the surface A, with an extension pattern 113 consisting of a conductor pattern different from the ground pattern 111 and feed pattern 112 and extending furthermore in contact with the return part 123. <P>COPYRIGHT: (C)2013,JPO&INPIT |
