The design and fabrication of a W‐band 64 element slot antenna array based on the substrate integrated waveguide structure is presented in this communication. The prototype antenna array is fabricated on a liquid crystal polymer substrate using standard printed circuit board (PCB) manufacturing processes. Characterization of the unbalanced antenna is accomplished through the use of a millimeter‐wave diode detector circuit, which is integrated onto the antenna array. Measurements show a beamwidth of approximately 13.2°. The maximum sensitivity of the antenna array with the diode detector is 121 mV/mW at 96 GHz. The total size of the antenna array with detector circuit is 4 × 3 cm 2 . © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:1825–1830, 2013
