“…In comparison to previous research, the suggested antenna offers a wider frequency range that is available [6,7,10,22,31]. Moreover, the size of the present work is also smaller than [5-7, 9, 10, 19], and the gain is better than [6,30,31].…”

“…This spectrum, designated for low-power output applications, extends from 3.1 to 10.6 gigahertz [2]. The combination of UWB and MIMO enables higher data speeds and more dependability in wireless communication systems, allowing for increased transmission range without an increase in the antenna's radiated power [3][4][5][6][7][8][9][10][11][12].…”

In this paper, a novel, highly isolated ultra-wideband multiple-input, multiple-output antenna design for indoor communication is proposed. The overall size of the antenna is only 36 × 36 mm 2 , and it contains four monopole antenna units and a fan-shaped isolated structure. Each antenna cell is composed of a U-shaped patch element and a defected rectangular ground structure. The fanshaped decoupling structure effectively absorbs coupling currents, significantly improving isolation. As a result, the proposed antenna system can cover the entire ultra-wideband and receive a resonant frequency of 2-11.08 GHz. The results demonstrate that the antenna's isolation is greater than 15 dB in the operating band. Furthermore, the antenna exhibits good radiation characteristics and reasonable envelope correlation coefficients.
