PASSIVE DEVICE FOR INCREASING TRANSMISSION EFFICIENCY OF HIGH FREQUENCY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an efficient transmission device for increasing transmission efficiency without increasing output power.

SOLUTION: The present invention relates to a conductive container closed with a wall (31) having an inner face and an outer face and including a passive resonance circuit (5). The passive resonance circuit (5) is physically divided into a first portion (15) and a second portion (16) and the first portion (15) and the second portion (16) are electrically connected with each other by an electric conductor (12). The whole of the first portion (15), the second portion (16) and the electric conductor (12) are disposed on the outer face of the wall (31) and the first portion (15) and the second portion (16) are disposed in areas which are positioned oppositely to each other on the outer face of the wall (31).
