- W4386823073 abstract "We have developed an all-optical fiber link antenna measurement system for a millimeter wave 5th generation mobile communication frequency band around 28 GHz. Our developed system consists of an optical fiber link an electrical signal transmission system, an antenna-coupled-electrode electric-field (EO) sensor system for 28 GHz-band as an electrical signal receiving system, and a 6-axis vertically articulated robot with an arm length of 1 m. Our developed optical fiber link electrical signal transmission system can transmit the electrical signal of more than 40 GHz with more than -30 dBm output level. Our developed EO sensor can receive the electrical signal from 27 GHz to 30 GHz. In addition, we have estimated a far field antenna factor of the EO sensor system for the 28 GHz-band using an amplitude center modified antenna factor estimation equation. The estimated far field antenna factor of the sensor system is 83.2 dB/m at 28 GHz." @default.
