UWB MIMO antenna with 4-element, compact size, high isolation and single band rejection for high-speed wireless networks

Abstract In this paper, a miniaturized size UWB 4-element MIMO antenna with band rejection feature is introduced. The four elements have rectangular radiator curved edges and partial ground plane an etched slot to enlarge the bandwidth of suggested structure operate from 3 up 12 GHz S 11 ≤ − 10 dB. high isolation between was achieved by forming antennas orthogonally without adding decoupling simplify design. design has 47 × mm 2 placed on low price FR4 substrate. A simple into achieve desired rejection. simulated tested outcomes operated extended within 3.3 4.3 eliminate interference WIMAX applications more than 22 dB ports. Also, fulfills peak gain 3.5 dBi, envelope correlation coefficient(ECC) < 0.005, diversity (DG) 9.98 channel capacity loss (CCL) 0.4 bit/s/Hz operating bands. good consistency which made be used in systems.
