| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a helical antenna structured to easily fix a spirally wound conductor inside a cover. SOLUTION: In a helical antenna comprised of a spirally wound conductor 1, a power feeding connector 3 and a cover 2 overlaying the conductor 1, unwoven fabric 15 is disposed between a distal end part of the spiral conductor 1 and the cover 2. Elasticity of the unwoven fabric 15 enables the conductor 1 and the cover 2 to be fixed by pressing the conductor 1 onto inner walls of the cover 2. A supporting part 4 is disposed on a power feeding part 2, and the supporting part 4 is fitted to an open end of the cover and fixed. COPYRIGHT: (C)2011,JPO&INPIT |
