Abstract
In this paper, a 2X2 MIMO array of crossed elliptical-shaped monopole antenna for dual-band application is presented. The proposed single antenna layout consists of two elliptical radiators with 45° inclination on the top layer and a partial stepped-ground plane in the bottom layer. The two layers are separated by rogers substrate with a dielectric constant of 4.5 and a thickness of 1.6 mm. The proposed single antenna produces resonance at 2.46 GHz and 5.17 GHz, with a return loss of 27.64 dB & 33.10 dB and gain of 2.69 dBi & 2.53 dBi respectively. Then the proposed layout is modified to a $2\mathrm{x}2$ MIMO array with elements arranged perpendicular to each other to decrease mutual coupling among multiple radiators. Additionally, a decoupling structure is utilized in the ground plane to enhance the isolation. A substantial increase in the return loss and low ECC values are observed. Increased gains of 5.23 dBi & 5.32 dBi are observed. The proposed monopole antenna offers dual-band operation with improved gain, making it a more suitable choice for wireless communication systems.
