| Abstract(in English) | International organizations such as IEC. CISPR and CENELEC are working for early finalization of the EMI test methods in microwave frequency bands including UHF, SHF and EHF. Recently the CISPR Yokosuka conference held on November 1997 established agreements on such conditions to design the EMI site used over frequencies 1 Ghz or higher as; (1) open-area test site to be of free-space type, (2) test distance to be 3-m, (3) no restriction for the alternative test site type, (4) insuring far-field condition (for test distance ≦ 2a^2/ λ where [a] is antenna aperture size and λ is wavelength and (5) EUT to be positioned within the main lobe of antenna (within -ldB angle range). This study report shows attainment of the free space as the international requirement through a simple method using multiple U-fence to remove waves reflected over the ground plane. The microwave test bench means a working desk for measurement of the microwave ENI and ofgeneral research and engineering. And it is a small type, light weight and knockdown type test site that facilitates transportation as required. The far-field condition indicated by CISPR is desirous to be deleted because it may lead to a conflict with application of various design elements. |
