| Abstract(in English) | Electro-optic sensing, which uses a dielectric electro-optic (EO) crystal, is very promising for the near-field measurement of antennas, because of its extremely small invasiveness. Previous EO measurement systems employ CW electrical signal generators, which are synchronized with lasers in CW or pulse operation. Above 100 GHz, electrical signal generators are rather expensive and bulky. We study a CW homodyne detection system for the antenna measurement; THz electrical signals are generated by using two wavelength tunable lasers and a photodiode(PD), and they are detected by using the EO sensor together with the same lasers. However, measurement stability is poor, because the change in wavelength of lasers causes a fluctuation of the sensitivity. In this paper, we report the near-field measurement system that can solve this stability problem, and show successful measurement of microwave and millimeter-wave antennas. |
