A Low-Profile and High-Gain Frequency Beam Steering Subterahertz Antenna Enabled by Silicon Micromachining
IEEE Transactions on Antennas and Propagation, 2020Co-Authors: Adrian Gomez-torrent, Maria Garcia-vigueras, Laurent Le Coq, Adham Mahmoud, Mauro Ettorre, Ronan Sauleau, Joachim OberhammerAbstract:A very low-profile sub-THz high-Gain Frequency beam steering antenna, enabled by silicon micromachining, is reported for the first time in this paper. The operation bandwidth of the antenna spans from 220 to 300 GHz providing a simulated field of view of 56°. The design is based on a dielectric filled PPW leaky-wave antenna fed by a pillbox. The pillbox, a two-level PPW structure, has an integrated parabolic reflector to generate a planar wave front. The device is enabled by two extreme aspect ratio, 16 $\times$ 16 mm large perforated membranes, which are only 30 $\mu \text{m}$ thick, that provide the coupling between the two PPWs and form the LWA. The micromachined low-loss PPW structure results in a measured average radiation efficiency of −1 dB and a maximum Gain of 28.5 dBi with an input reflection coefficient below −10 dB. The overall Frequency beam steering frontend is extremely compact (24 $\times$ 24 $\times$ 0.9 mm) and can be directly mounted on a standard WM-864 waveguide flange. The design and fabrication challenges of such high performance antenna in the sub-THz Frequency range are described and the measurement results of two fabricated prototypes are reported and discussed.
