摘要

This research article introduces a high-gain multiple input multiple output antenna design with an F slotted in Coplanar Waveguide that enhances isolation, gain, and provides a broad bandwidth suitable for wireless Ultra-Wideband applications. Antenna design features a low-profile formation with four elements constructed on an FR-4 substrate. The antenna is resonant at two frequency 4.7 GHz and 8.4 GHz and has a wide bandwidth 1.9–15 GHz, the isolation between all ports of the antenna is greater than 50 dB at the resonant frequencies of 4.7 GHz and 8.4 GHz.This implies very small coupling between ports, less than 0.001% power input coupled, hence a high degree of signal isolation that minimizes mutual interference. the antenna maintains a threshold isolation of 20 dB throughout the band from 1.9 to 15 GHz for reliable performance with minimal port-to-port interference. This MIMO antenna demonstrates a remarkable efficiency lies between 80 and 90%. Additionally, this antenna structure deals with a diversity gain of 9.9 dB and achieves an envelope correlation coefficient value of around 0.44. Channel capacity loss of the antenna is less than 0.2. Furthermore, this antenna resonance in two frequencies is 4.7 GHz and 8.4 GHz. The electrical dimensions of antenna are 1.69λ0 × 1.69λ0 × 0.045λ0. The fractional bandwidth is approximately 155.09% is excellent for ultrawideband. This antenna is ideal for short-range applications such as WPAN and sensor networks. It’s also well suited for higher frequency uses like real-time location systems, large-scale meteorological data transmission radar, imaging, and ADAS technology.
