In this paper, a 135 GHz imager array of 16 pixels is developed for non-invasive biomedical or security scanning. The system consists of 4x4 of arrayed CMOS detectors and sources. Each of the source or detector pixel has an antenna for radiating or detecting millimeter-wave signal, respectively. The antenna array is built on Roger 5880 PCB substrate. The CMOS source and detector chips are developed using 65-nm CMOS technology. To minimize crosstalk due to surface wave radiation (SWR), surface wave resonators are placed between antennas for system integration. The isolation between adjacent antennas is enhanced by around 8-15 dB over frequency range of 120-140 GHz. The imager system detects the signal radiation of 60-mV, above the noise floor at the distance of 15-cm between the source and detector board.
