Design & characterization of an antenna system for UWB-MIMO communications systems

In this paper, an antenna system is presented which is designed and analyzed for the wireless communication systems using Ultra-Wideband (UWB) technology combined with Multiple-Input Multiple-Output (MIMO) technique. The proposed planar antenna system consists of two heterogeneous antenna elements integrated on the same substrate. The presented antenna system works efficiently in the frequency range of 3.1–10.6 GHz. The parameters like reflection coefficient, gain, mutual coupling between the elements, correlation coefficients, diversity gain and total active reflection coefficient have been simulated to verify the functionality of the antenna system having the dimensions of 30 × 85 mm².
