UWB MIMO optical transparent antenna based on ITO film

An optical transparent antenna using indium tin oxide (ITO) for ultra-wideband (UWB) multiple-input multiple-output (MIMO) applications is proposed. The ultrathin ITO film coated on a 67×67mm2 glass substrate and over 85% transparency achieved. consists of four coplanar waveguide (CPW)-fed elements with rotationally symmetric placement. adjacent are placed orthogonally to produce dual polarisation reduce coupling. MIMO operates from 1.5 11GHz which covers the UWB applications. coupling between less than -23dB. Mean effective gain (MEG), envelope correlation coefficient (ECC) diversity (DG) achieve excellent values guarantee good performance. prototype verified measured results analysed.
