“…Meanwhile, the measured realized gain is higher than 30 dBi, and its corresponding antenna efficiency is higher than 45% over the frequency range of 58-66 GHz. According to our investigation, the main contribution to the critical degradation in the measured realized gain comes from the actual loss tangent of RT/duroid 6002 in the V-band, which must be much larger [27] than that listed in the catalog. According to [28], its dielectric constant and loss tangent are respectively 3.08 and 0.0028 in the V-band.…”

A single-layer corporate-fed substrate integrated waveguide slot array antenna is newly proposed and verified. It is characterized by low profile, easy fabrication, low cost, low sidelobes, wideband operation, and high efficiency. A V-band 16 × 16-element array with uniform excitation is designed for demonstration. The radiating elements and feeding waveguides are arranged within a single-layer substrate, whose dielectric constant and loss tangent are appropriately selected. By adopting the full-corporate feed, the 16 × 16 radiating slots are excited by the 16 × 16 output ports of the feeding circuit, which is composed of cascaded H-plane T-junctions. For further bandwidth improvement, a metal grid plate is introduced on the top of the radiating slots. The test antenna is fabricated by the conventional PCB process. The measured bandwidth for |S 11 | < −10 dB is 16.2%, fully covering the 57-67 GHz frequency range. Meanwhile, the measured antenna gain higher than 30 dBi associated with the antenna efficiency higher than 45% is achieved over the 58−65 GHz frequency range.INDEX TERMS Slot array antenna, substrate integrated waveguide, single-layer structure, full corporate feed, broadband design.
