shield surrounding each pixel. This layout symmetry enabled a wide-band radially symmetric antenna pattern. The silicon die (15Ω-cm resistivity) was thinned down to 150µm and active layers were selectively blocked to minimize substrate incurred losses. The simulated radiation efficiency of the antenna radiating into a hypothetical semi-infinite lossless silicon substrate through the die is about 70 to 77% from 0.8 to 1THz. 1 2 Future imaging applications in the submillimeter-Wave range (300GHz to 3THz) require RF systems that can achieve high sensitivity and portability at low power consumption levels. In particular, CMOS process technologies are attractive due to their low price tag for industrial, surveillance, scientific, and medical applications. Recently, CMOS-based detectors have shown good sensitivity
