Özet

The influence of an aperture area (between 2λ2 and 11λ2) on the Shielding Effectiveness of metallic enclosures has been measured in an anechoic chamber, and wavelength dependent SE measurements are introduced. Measurement setup was established operating between 6GHz to 13GHz. While the width/ length ratio varies from 1 to 16, shielding effectiveness gets better by about 6.5dB at low level frequencies, reaches about 10dB at higher frequency band, and they get closer each other at around resonance frequencies. © 2011 IEEE.
