Design of Compact MIMO Antenna for 5G/Ultra-Wideband Communications

Abstract

In this contribution, a compact 13 GHz notched band Multiple-Input Multiple-Output
(MIMO) antenna is accessible for Ultra-Wide Band/broadband communication in metric
linear unit wave band. The antenna structure has been designed on one substrate of FR-4 of
thickness 1.6 mm. Two symmetrical microstrip patch antenna elements positioned in vertical
direction to realised better diversity performance. The antenna elements are made up of a
rectangular patch with microstrip feed line, operatingon the frequency of 28 GHz for Ultrawide band applications. The result of designed structure has been computed numerical by
FEM based solver HFSS v 13. From the simulation results, it is clear that the proposed
MIMO antenna structure covers 24.048 GHz to 37.04 GHz with impedance bandwidth of 13
GHz (S11 better than -10dB) and also the isolation is found better than -20 dB in full
wideband application. The gain of proposed MIMO antenna designed structure has found
approximately 2.11 dB.
