Design of Dual-Element Tri-Band (DETB) MIMO antenna with improved isolation A Dual-Element Tri-Band (DETB) by cleft and bifurcation based Multiple Input Multiple Output (MIMO) antenna is designed for Long Term Evolution Advanced (LTE-A) and Global positioning system (GPS) wireless applications. As part of DGS, a T-shaped structure is used in the ground plane with dual H-shaped slot is etched from it to improve the isolation between the antennas. The overall size of the MIMO antenna is 50 × 90 × 1.54 mm3.
