Dual-Beam Planar D-Band Antenna Array: Filtering Patch Antennas and Dielectric Lens
This paper presents a D-band (150-170 GHz) <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$16 \times 2$</tex> planar patch antenna array, integrated with a dielectric lens, designed to facilitate dual-beam (hybrid) beamforming capabilities. The configuration employs both the array factor and the lens to achieve beam collimation across distinct focal planes. The patch antenna array elements are designed based on a band-pass filter topology on high-resistive silicon substrate, and optimized for the PTFE dielectric lens material situated atop the array. The extruded elliptical dielectric lens with the patch antenna array reported in EM simulation a gain of 26.8 dBi and scan angle of +/−30° at 150 GHz. Furthermore, an asymptotic analysis method has been employed to investigate the variations in beam tilt relative to the size of the dielectric lens.
