| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Radiated emission(EMI) measurement method over 1 GHz is specified to CISPR16-2-3 and VCCI will regulate radiated emission over 1 GHz in 2010. In the regulation, if the 3dB beam-width of receiving antenna is narrower than vertical size of EUTs, the height scanning of receiving antenna is needed. If we measure radiated emission of large size EUTs with height scanning of receiving antenna, we need more measuring time. To reduce measuring time of radiated disturbance over 1 GHz, the 3dB beam-width of antenna needs to be wider than vertical size of EUTs. We made the beam forming antennas for measuring radiated emission over 1 GHz without height scanning of receiving antenna for large size EUTs. Since the beam-width of the antenna system is 53.2 degree, it can measure EUTs under 3m height without height scanning. And we confirmed the radiated emission was able to measure electric field strength 3dB low for the limit value by securing the margin of 10dB for the noise floor of the measurement system by using the antenna system. | |
