Abstract

The next significant development in wireless communication is the shift to 6G technology, which expands upon 5G's innovations and incorporates new features and technologies. 6G is anticipated to reach ultra-high data speeds, possibly in the terabits per second (Tbps) level, by using the terahertz (THz) band (0.1–10 THz). This article explores the distinct design of the Pentagonal edged microstrip patch antenna (PEMPA) structure and examines antenna performance. Further, the structure is embedded with a unique rhombic air-pored photonic crystal (PhC) substrate and simulated using the CST tool. To improve the antenna's performance, the investigation continues to optimize the PhC air hole size and lattice constant value. The proposed unique PhC-based PEMPA achieved remarkable antenna properties, including -77.66 dB (RL), 8.752 dB gain at 2.06 THz, and a high data rate in the Tbps range. The goal of the suggested antenna is to achieve sub-millisecond latency, which is essential for real-time uses in machinery automation, automatic vehicle operation, and robotic surgery..
