Abstract

A quad-port wheel-shaped MIMO patch (QWMP) antenna featuring a circular complementary split-ring resonator (CSRR) slot is proposed for 6G terahertz communication. The radiating elements are configured in a pattern diversity arrangement to enhance diversity performance and minimize mutual coupling. The QWMP antenna is fabricated on Kapton polyimide with overall dimensions of 400 × 400 × 20 µm³ . It exhibits a wide bandwidth (S₁₁ < − 10 dB) of 0.94 THz, covering the range from 1.93 THz to 2.87 THz. The QWMP antenna achieves a high gain of 8.12 dBi and 9.41 dBi at 2.00 THz and 2.75 THz, respectively. The values of ECC < 0.001 and DG > 9.995 indicate that the QWMP antenna has excellent diversity performance, making it suitable for high-speed, lowlatency 6 G communication systems. The simulated results of key antenna parameters, including radiation patterns, gain, and diversity characteristics, are examined and presented. The proposed antenna demonstrates significant potential for next-generation terahertz communication applications.
