2-element MIMO Antenna Design using Triangle-strip applicable for n258 band

A 2-element MIMO (multiple-Input Multiple-Output) antenna operating in n258 band (24.39 GHz ~ 26.42 GHz) of millimeter wave for future 5G communication is proposed. Single element antenna has a size of 15 mm × 15 mm. Triangle strips are the key element for the design of single element, where heights of triangle strips is arranged in Fibonacci series. Further 2-element antenna with overall size 15 × 25 mm

is suggested for MIMO application with satisfied S-parameter, ECC, DG and MEG values.
