Title:
周波数微調整機構付きアンテナ
Document Type and Number:
Japanese Patent JP6862006
Kind Code:
B2
Abstract:
To provide an antenna with a frequency fine adjustment mechanism capable of easily fine-tuning a resonance frequency of a loop antenna and its variant, hentena antenna after production.SOLUTION: The antenna includes a loop antenna 11 set to make a resonant frequency slightly higher than a radio frequency or a rectangular shaped conductor plate 18 with one side connected to a first long side 12 of a hentena antenna 23. By adjusting a distance d between the other side of the conductor plate 18 and a second long side 13, the resonant frequency of the loop antenna 11 or the hentena antenna 23 is fine-tuned to match the radio frequency.SELECTED DRAWING: Figure 1
