Title:
RADIO-WAVE ABSORPTIVE STRUCTURE OF TRANSPARENT PLATE, WINDOW MEMBER AND FRAME
Document Type and Number:
Japanese Patent JPH08116197
Kind Code:
A
Abstract:
PURPOSE: To provide a radio-wave absorptive structure of a transparent plate, in which radio-wave interference caused by a public radio wave reflected by a building and scattered or diffracted can be prevented.
CONSTITUTION: A transparent plate 1 has a plurality of antenna coil elements 3. A capacitance element 4 is connected to each coil element 3 to form a plurality of resonance circuits with different resonance frequencies. A resistance element 5 is connected to each resonance circuit to attenuate a resonance current.
