A High-Gain Beam Steering Silicon Based Antenna Array for Sub-MmWave Applications

In this paper, we are presenting a low-cost and high-gain beam steering silicon-based antenna array for submmWave and THz applications, specifically for the next generation of 5G and radar systems. The antenna element is a parasitic tapered antenna for enhancing the gain while the size of the array is kept small. The beam steering happens by movement of a small metal sheet above each arm of the antenna array. The achieved gain of the system is 15.4 dBi at 86 GHz. The total scanning angle of 20 degrees is observed.
