Partially Reflected Surface (PRS)-Loaded Graphene-Based Patch Antenna for 6G
Abstract
This work investigates a slotted patch antenna integrated with a partially reflected surface (PRS) to operate in the TeraHertz (THz) frequency range for 6G. The antenna is based on graphene material, on a Rogers RT Duroid 6010 substrate. The proposed antenna achieves a bandwidth of 70 GHz (750 GHz to 820 GHz). The PRS sheet consists of 5x4 unit cells, which are optimised to enhance the overall realized gain of the antenna. The overall realized gain has increased by 1.07 dBi. Also, the PRS enhanced the antenna radiation pattern, showing stable properties over the operating bandwidth. The improved antenna performance is validated via simulations.
