Design and Analysis of a Multi band Array Antenna on HR- Silicon for 6G and Beyond Wireless Communication

This paper presents the design and simulation of a silicon substrate-based patch antenna array for operation at the THz frequency band for future 6G wireless communication systems. A coaxial feed network is utilized for equal power division and phase alignment of the four radiating elements, which is extremely crucial for better directional performance. The Structure is simulated with ANSYS HFSS, a full-wave electromagnetic simulator for terahertz-frequency structures. Silicon substrate is utilized due to its integration with integrated circuit technology and capability to facilitate high-frequency miniaturization. Simulation studies indicate the antenna hold a maximum gain of 12.68 dB, along with suitable impedance matching and stable broadside radiation pattern. These characteristics make the suggested antenna array highly appropriate for short-range, ultra-high-speed wireless communications within 6G networks. The paper demonstrates the performance of microstrip-based THz antennas and gives an insight into feed structure optimization and material selection for high-frequency systems.
