Abstract

Multi-input multi-output (MIMO) antennas have garnered significant attention for addressing the demands of high channel capacity, reliable and uninterrupted signal transmission, and high data rates, especially with recent advancements in 5G low Earth orbit (LEO) satellite communications. In addition to these features, automotive applications require antennas with minimal mutual coupling, high gain, multiple resonant frequencies, and compact size for user equipment. To meet these requirements, a 1 × 2 defected ground structure (DGS)-based fractal MIMO antenna array is proposed, covering various frequencies in the sub-6 GHz bands, including 0.7 GHz, 2.6 GHz, 3.1 GHz, and 3.5 GHz. The proposed antenna provides sufficient channel bandwidths and achieves a gain of 12.9 dBi in the n78 frequency band. The design has been fabricated, and the measured results show good agreement with the simulated ones. Moreover, the proposed antenna design can be integrated into the plastic parts of a car body, offering various automotive applications. It achieves a realistic data rate of approximately 10–12 Mbit/s, as verified through link budget calculations that consider the key parameters of LEO satellite systems.
