SMALL-SIZED ANTENNA

摘要

PROBLEM TO BE SOLVED: To manufacture a small-sized antenna which has a radiation conductor 12 and a ground conductor 14 opposite to each other by using a metal mold in simple structure. SOLUTION: A dielectric layer 30A which has an engagement projection part 34 is formed on the surface of the radiation conductor 12 which faces the ground conductor 14, and a dielectric layer 30B which has an engagement recessed part 32 is formed on the surface of the ground conductor 14 which faces the radiation conductor 14. The dielectric layers 30A and 30B are coupled together by engaging the engagement recessed part 32 and engagement projection part 34 with each other and the radiation conductor 12 and ground conductor 14 are held at a specified interval.
