Title:
TUNING METHOD FOR HELICAL ANTENNA RESONANT FREQUENCY AND HELICAL ANTENNA
Document Type and Number:
Japanese Patent JP2002076754
Kind Code:
A
Abstract:
To provide a helical antenna resonant frequency tuning method which can easily conduct resonant frequency tuning.
The method comprises a process for preparing a helical antenna with a resonant frequency higher than desired, which has a column-shaped member 11 with a dielectric constant higher than the air and the one end 11a of the member can be exposed by digging and, and a process for digging the central part of the one end 11a of the member 11.
