In this paper, a miniaturized, dual channel Multiple Input Multiple Output (MIMO) antenna array is presented for Ultra Wideband applications. The array configuration is well suited for 3-D system-in-package applications. MIMO antennas are reported in two different configurations, i.e., back-to-back and orthogonal/corner. The array is designed on an FR-4 substrate of thickness 1 mm and compact dimensions of 40 mm × 35 mm. An Interdigital FSS based decoupling structure is analyzed and deployed to reduce mutual coupling between array ports. Simulated and measured results show that an isolation better than 20 dB is achieved over most of the band. More importantly, other performance criteria such as envelope correlation coefficient, total active reflection coefficient, channel capacity loss and gain also indicate that the proposed array is a potential candidate for UWB-MIMO applications.
