| Abstract(in English) | Antenna-coupled-electrode electro-optic (EO) modulators operating in the 28-GHz band were analyzed, designed and fabricated for the applications to the next generation (5G) mobile wireless communication systems and to the precise antenna measurement systems for 5G base stations. By analyzing the antenna-coupled electrode in detail with the 3-dimensional model of an EO-crystal-film and a low-k glass plate stacked structure, the electric field enhancement factor of about 8,000 times of the irradiated 28-GHz field can be induced along a standing-wave modulation electrode, which enables us to have a compact wireless-optical signal converter without external power supply. The designed EO modulator was fabricated using a 50-?m-thick LiNbO3 crystal film and a 250-?m-thick SiO2 base substrate and its signal conversion characteristic from the 28-GHz band wireless to optical signals were demonstrated successfully in the experiment. |
