Title:
DEVICE FOR REDUCING DISTURBANCE ELECTROMAGNETIC WAVE
Document Type and Number:
Japanese Patent JP2006210703
Kind Code:
A
Abstract:

To provide a device for reducing a disturbance electromagnetic wave wherein reduction effect of jamming electromagnetic wave can be obtained in a wide range.

The device is constituted of a conductive plate 1 constituted of a conductive material and a resistor 2. The conductive plate 1 is made a self-complemental structure for electrically joining the resistor 2. Consequently, a voltage is generated in the resistor 2 through resonance at a frequency of a wide range as for radiation electromagnetic wave from a dipole antenna 3. In the process, a current flows to the resistor 2 and Joule's heat is generated, thus reducing electromagnetic noise in a wide range frequency.
