The present work deals with design of a modified back to back E-shaped patch antenna with improved bandwidth and isolation characteristics. The proposed antenna resonates at 14.16 GHz & 15.47 GHz frequencies for VSWR < 1.34, giving an impedance bandwidth of 20%. A 2×2 MIMO is developed by using the proposed antenna with a reduced mutual coupling of -37 dB. The results for various antenna parameters like radiation pattern, gain, return loss, mutual coupling, and bandwidth are furnished in this paper.
