Abstract

A compact receiver module for a 94 GHz band passive millimetre-wave (PMMW) imaging system is developed. This receiver module consists of an antipodal linearly tapered slot antenna (LTSA) and microwave monolithic integrated circuit (MMIC) with flip-chip bonding assembly that provides high radio frequency (RF) performance at low cost. A new microstrip-slot transition developed for the LTSA/MMIC interface is also presented and the design procedure for the LTSA is discussed, which obtains almost the same E- and H-plane beam widths. In addition, a low-noise, high-gain MMIC is discussed using inverted microstrip lines that are developed. Finally, it is shown that the PMMW imager can generate a millimetre-wave image.
