Recent progress in electromagnetic compatibility (EMC) technology has created a need for small and wideband antennas that can be used to measure the quality of EMC measurement facilities and to measure electric field strength for immunity tests and human hazard studies. Antennas using fiber optics are being developed because this kind of antenna has the wideband property and can eliminate the influence of the coaxial cable. This paper first summarizes the development of fiber optic antennas for EMC measurement and the construction of practical fiber optic antennas. It then describes the recent progress that has been made in Japan. This progress includes the electromagnetic source and the electric field sensor using a spherical dipole antenna with O/E or E/O converters, and it includes a wideband electric field sensor using electro-optical crystals.
