“…It also simplifies the layers of the multiple accesses and upturns the robustness along with the reduction of the air interface potential. 12 Reduction of mutual coupling is one of the major constraints in MIMO antenna design. 13 It is also desired that the envelope correlation coefficient (ECC) should be very low along with higher diversity gain (DG) for a good MIMO antenna system.…”

This communication presents a compact wide band wearable MIMO antenna with very low mutual coupling (VLMC). The proposed antenna is composed of Jeans material. Two “I” shaped stubs are connected in series and are employed on the ground plane between the two patches separated by 0.048 λ to increase isolation characteristics of the antenna‐port. The antenna covers frequency spectrum from 1.83 GHz to 8 GHz (about 125.5%) where the minimum port isolation of about 22 dB at 2.4 GHz and maximum of about 53 dB at 5.92 GHz are obtained. The envelope correlation coefficient (ECC) of the MIMO antenna is obtained to be less than 0.01 with a higher diversity gain (DG > 9.6) throughout the whole operating band. The proposed MIMO antenna is cost effective and works over a wide frequency band of WLAN (2.4‐2.484 GHz/5.15‐5.35 GHz/5.72‐5.825 GHz), WiMAX (3.2‐3.85 GHz) and C‐band downlink‐uplink (3.7‐4.2 GHz/5.925‐6.425 GHz) applications. Simulation results are in well agreement with the measurement results.

“…MIMO antennas can also be used to increase the transmission capability and can also improve the spectral efficiency. It can also be used to simplify multi-access layers and also to reduce air interference [22]. Because of the presence of multiple antenna elements, the mutual coupling that occurs in the MIMO system design should be reduced as far as possible [23].…”

This communication presents a compact dual element wearable ultrawideband (UWB) multi-in multi-out (MIMO) antenna with increased port isolation. The suggested design consists of a jeans substrate in which a tree fashioned stub comprising of 8(eight) branches is introduced in the middle position of the partially etched antenna ground for improving the characteristics of port isolation. The proposed design occupies the frequency spectrum operating from 1.71 to 12.63GHz (impedance bandwidth of around 152.3 percent) and satisfies the bandwidth demands for WiMAX (3.2-3.8 GHz), WLAN (5.15-5.35/5.72-4.85 GHz), the C Downlink-uplink bands (3.7-4.2/5.9-6.425GHz), ITU bands (8-8.5GHz) and the downlink defense band (7.2-7.5GHz). The antenna is able to maintain isolation between the ports of > 22dB across the entire UWB frequency spectrum. The coefficient of the envelope correlation for the whole operating band was observed to be < 0.012 along with a very high diversity gain > 9.9. The channel power loss of the proposed wearable UWB MIMO antenna is found to be < 0.27 bit/s/Hz. The suggested UWB MIMO antenna, fascinated with optimization, covers an area of 35 x 35 mm 2. The suggested design is also able to perform satisfactorily when attached on-body. Simulation and testing fairly identified the performance of the antenna and rendered it to be an upstanding choice for wearable UWB applications.

A lightweight multi‐input multi‐output (MIMO) two‐element wearable ultra‐wideband (UWB) antenna having a port isolation of greater than 21 dB is introduced in this communication. The proposed structure includes wearable jeans cloth as a substrate, wherein two inverted u‐formed stubs are mounted in the middle position located on the backside of antenna and attached to the partially etched ground for enhancing the characteristics of port isolation. The developed UWB MIMO antenna has a size of 50 x 35 mm2 and covers the frequency range operating from 1.83 to 13.82 GHz (~153.2%). The suggested MIMO antenna is inexpensive and functions across a broad frequency range of applications including WLAN (2.4‐2.484 GHz/5.15‐5.35 GHz/5.72‐5.825 GHz), Downlink‐uplink WiMAX (3.2‐3.85 GHz), and C‐band (3.7‐4.2 GHz/5.925‐6.425 GHz). The diversity gain (DG) is found to be greater than 9.9 along with envelope correlation coefficient (ECC) to be less than 0.059 across the entire operating bandwidth. The proposed MIMO antenna's channel power loss is bestowed to be less than 0.35 bit/s/Hz. The SAR results of the proposed UWB MIMO design admits that the antenna performs satisfactorily and is suitable for wearable applications. Simulation and testing fairly proved the output of the proposed antenna as a righteous candidate applicable for UWB MIMO applications.
