In this paper, we present a compact antenna for 5G new radio (NR) and Wi-Fi 6 applications.Using characteristic mode analysis (CMA), two orthogonal modes have been separated and then a gap-coupled shaped feed-line has been used to UNBLEACHED LECITHIN excite the radiator.An open stub is added to achieve the wide operating bandwidth of the antenna.

The size of a single antenna element and the 1 $ imes $ 2 array-unit (AU) are 20 $ imes $ 21.5 mm2 and 40 $ imes $ 21.5 mm2, respectively.

The operating and fractional bandwidths (FBW) of the AU are 5.18–7.71GHz and 39.

25%, respectively.The proposed AU is used to develop a number of radiating element-independent multiple-input-multiple-output (MIMO) Toddler Diaper Covers antennas comprising of 2AUs, 4AUs, and 8AUs with identical electrical characteristics and good isolation ( ${I}$ ) ≥ 18.8 dB.

All the AUs have realized gain ~ 3.0 dBi, and the total antenna efficiency ~ 70% making it suitable for the single-user MIMO (SU-MIMO) and multiple users MIMO (MU-MIMO) needed for Wi-Fi 6 applications.To show the application of these antennas, the deployment scenario of a 16AUs MIMO antenna on a large size ground plane which mimics the smart TV panel and router chassis, etc.

, is also presented.These AUs may find potential applications in radiator-number independent MIMO systems.
