TWO-RESONANCE HELICAL ANTENNA CAPABLE OF SUPPRESSING FLUCTUATION IN ELECTRIC CHARACTERISTIC WITHOUT RESTRICTION IN SIZE OF A HELICAL COIL |
| 摘要 |
In a two-resonance helical antenna, a single helical coil (3) is made of a conductive material and extends in one axis direction. An annular conductor portion (5) is arranged around the helical coil in a coaxial fashion to be spaced and insulated from the helical coil. The annular conductor portion is positioned 1n the middle of the helical coil in the one axis direction. |
