A LOW COST 8 X 8 W-BAND SUBSTRATE INTEGRATED WAVEGUIDE ANTENNA ARRAY DETECTOR ON LCP
01 August 2013
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 degrees. 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 x 3 cm2. (c) 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:1825-1830, 2013
