Design and Analysis of Sunshine‐Shaped MIMO Antenna for High Demand in Data Rates and Ultra‐Fast Sixth‐Generation Wireless Communications Through THz Spectrum Range

ABSTRACT THz antennas, which function at high speeds, frequencies, and data rates, were developed in response to the increased need for high‐speed communication equipment. High data transfer is necessary for wireless communication in modern technologies. After 5G, the next generation of wireless technology is called 6G (sixth‐generation wireless). Because 6G networks may run at greater frequencies than 5G networks, their capacity and latency will be significantly increased. Allowing communications with a latency of 1 μs is one of the objectives of the 6G internet. This paper introduces a compact and highly efficient sunshine‐slotted MIMO antenna designed for 6G and wireless applications. The antenna features a sun‐shaped patch and a partial ground layer to improve its overall performance. The proposed antenna operates across 3.6, 4.5, 5.2, and 6.2 THz, respectively, which are used for wireless communication systems. This work presents a MIMO antenna constructed with a low reflection coefficient value of −34, −38, −18, and −23 dB, with an insertion loss of less than −30 dB over the operational frequency. In addition to this, the antenna has a gain value of 8.5–9.2 dBi. The proposed MIMO antenna also has a minimum ECC value of < 0.01; similarly, across the operating frequency, the antenna has a DG value range of 10–11 dB respectively. The proposed antenna has dimensions of 33 × 33 × 100 μm 3 using graphene as a conducting layer and silicon as a substrate layer. The suggested antenna can be utilized for high‐speed communications because of its high gain and operating frequency applicability.
