Compact 2×1 Mimo Antenna System for Lte Band

“…Parasitic elements are used between the antennas to cancel part of the coupled fields between them by creating an opposite coupling field thus reducing the overall coupling on the victim antenna using parasitic tape and stepped impedance resonator as parasitic element [22,23]. A T-shaped ground stub with a slot is used between the two square monopole elements to reduce mutual coupling in [24].…”

Dual-Band Fractal Semi-Printed Element Antenna Arrays for MIMO Applications

“…This restriction leads to close positioning of MEA elements which is opposed to the requirement of high electromagnetic isolation between them and moreover to the limitation of MEA's gain. Various techniques have been proposed in the literature for facing these problems and simultaneously for the enhancement of MEAs' performance as a)the incorporation of uniform [1]- [2] and non-uniform [3]- [4] EBG lattices and b)the utilization of folded slots and parasitic elements [5]- [6] or the etching of slots in the ground [7]. Another technical specification of MEAs destined for modern communication systems is the dual or generally the multi-band [8], inverted L monopoles with shorting pins and slot etched ground plane [9] or reconfigurable multi-mode microstrip antennas [10] have been employed.…”
