Abstract (in Japanese) (See Japanese page) 
(in English) We propose a Si–CMOS terahertz image sensor to resolve the lack of low-cost and small-size detectors. The imager chip consists of an imaging pixel array and column ADCs. The imaging pixel consists of an on-chip antenna and an amplifier acting as envelope detector. The pixel used a microstrip patch antenna for receiving THz waves. However, these antennas’ narrow bandwidth and large ground-plane size cause major problems. We introduce an on-chip folded-slot antenna to reduce the pixel size, while keeping the gain. As a result, we successfully reduced the size of the imaging pixel, while keeping an antenna gain of 0 dBi over a broader bandwidth than the microstrip patch antenna. In this paper, we report it in detail.
