Research of the Distance of Transmitting Antenna and Test Window to Measure Shielding Effectiveness of Material Using Shielded Room Method

Abstract:

t has the certain request to the distance of transmit antennas and test window when measure the effectiveness of material using shielded room method. In order to obtain the shielding effectiveness of materials on the plane wave, far field emission state of the antenna should be ensured-distance of transmitting antennas and test window distance should be far enough. This paper presents a near-field shielding theory of a shielded room, explaining the effect of the distance on the shielding effectiveness measurement results fundamentally. The theory can be used to guide the test that measures shielding effectiveness of material using shielded room method.
