摘要：

—This paper proposes an improved design of a W-band slot array antenna, based on a ridge waveguide and a rectangular micro-coaxial line. To achieve a high gain and wideband antenna with element spacing smaller than half a wavelength, a broadband transition of rectangular coaxial line to ridge waveguide was designed. The improved design has bandwidth around 15.4 GHz (94.8 GHz– 110.2 GHz), and the simulated realized gain is about 14.6 dB. Measured results of the fabricated antenna demonstrate that the gain at theta = 0◦, and VSWR is better than 13 dB and 2.7, respectively. The antenna’s size is about 12 mm × 5.5 mm × 0.46 mm. © 2023, Electromagnetics Academy. All rights reserved.
