METAL GROUND PLANE OF OPEN TEST SITE FOR MEASURING OF ELECTROMAGNETIC WAVE NOISE

摘要

PURPOSE: To stabilize a ground reflected wave of an open test site for measuring electromagnetic wavenoise. ;CONSTITUTION: A ground plane of an open test side is covered with a metal gauze 7 on a concrete foundation ground 4 through a substrate adhesive resin layer 6, and the gauze 7 is convered with a coating resin layer 8. Since the gauze 7 is sealed with the layer 8, the temperature of the gauze 7 itself does not rise to 60°C or higher even in summer, and no thermal deformation occurs. Accordingly, a problem in which the gauze is so thermally deformed that radio wave reflection state is unstable is eliminated, the measured value has a good reproducibility, and its reliability is enhanced.;COPYRIGHT: (C)1994,JPO
