ABSTRACT = {A four-element compact dual-band patch antenna having a common ground plane operating at 28/38 GHz is
proposed for millimeter-wave communication systems in this paper. The multiple-input-multiple-output (MIMO)
antenna geometry consists of a slotted ellipse enclosed within a hollow circle which is orthogonally rotated with
a connected partial ground at the back. The overall size of the four elements MIMO antenna is 2.24λ × 2.24λ (at
27.12 GHz). The prototype of four-element MIMO resonator is designed and printed using Rogers RT Duroid 5880
with ε<sub>r</sub> = 2.2 and loss tangent = 0.0009 and having a thickness of 0.8 mm. It covers dual-band having a fractional
bandwidth of 15.7% (27.12–31.34 GHz) and 4.2% (37.21–38.81 GHz) for millimeter-wave applications with a gain
of more than 4 dBi at both bands. The proposed antenna analysis in terms of MIMO diversity parameters (Envelope
Correlation Coefficient (ECC) and Diversity Gain (DG)) is also carried out. The experimental result in terms of
reflection coefficient, radiation pattern, gain and MIMO diversity parameter correlates very well with the simulated
ones that show the potential of the proposed design for MIMO applications at millimeter-wave frequencies.},
