340-GHZ HETEROGENEOUSLY-INTEGRATED THZ IMAGER WITH 4°-BEAMWIDTH 16×16 IPD ANTENNA ARRAY FOR LENSLESS TERAHERTZ IMAGING APPLICATIONS

340-GHz Heterogeneously-Integrated THz Imager With 4°-Beamwidth 16×16 IPD Antenna Array for Lensless Terahertz Imaging Applications

A low-cost and planar heterogeneously-integrated 340-GHz THz imager is proposed for lensless THz imaging applications.The proposed THz imager is composed of a $16 imes 16$ antenna array realized sensationnel kiyari in an integrated-passive-device (IPD) technology, an IPD-to-CMOS THz interconnect, and a power detector implemented in a 0.18- $mu ext
