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.

In this article, a dual sense dual port circularly polarized cylindrical dielectric resonator antenna (CDRA) is discussed for multiple input multiple output (MIMO) applications. Three exclusive features of the proposed radiator are (i) modified circule‐shaped aperture generates circular polarization for both the ports; (ii) proposed structure can generate left‐hand circular polarization (LHCP) and right‐hand circular polarization (RHCP) that depends on feed port selection; (iii) by introducing the concept of polarization diversity (LHCP/RHCP) and defected ground structure (DGS) between the two radiator, isolation is improved. A prototype of proposed radiator is fabricated and experimentally tested to authenticate the simulated results. The fractional impedance bandwidth for port 1 and port 2 is 15.1% and 14.9%, respectively. Within the targeted operating band, the isolation is better than −25 dB between the ports. Different diversity performance parameters are also calculated and they are also lie within their optimum limit. The proposed MIMO antenna is suitable for WLAN (5.5/5.8 GHz) applications.

“…This helps to explain the performance related to the gain and environmental effect of the antenna. The MEG for both the ports of the diversity antenna can be calculated by using S‐parameters from the equations given below:

{MEG}_{1} = 0.5 η_{1, rad} = 0.5 ([], 1 - {|S_{11}|}^{2} - {|S_{12}|}^{2})

{MEG}_{2} = 0.5 η_{2, rad} = 0.5 ([], 1 - {|S_{12}|}^{2} - {|S_{22}|}^{2})

This communication describes a simple compact wide band multiple input multiple output (MIMO) antenna for Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) applications. The proposed antenna is integrated with an electromagnetic band gap (EBG) structure which is used to reduce the mutual coupling between the ports. The structure is excited by a line feed mechanism and investigated experimentally. The antenna covers the frequency range from 2.01 to 3.92 GHz with the corresponding fractional bandwidth of 64.42%. It fulfills the bandwidth requirements of WLAN (2.35‐2.5 GHz) and WiMAX (3.2‐3.85 GHz) bands where minimum port isolation is obtained around 29 dB throughout the entire application band. The proposed MIMO antenna has very low envelope correlation co‐efficient (ECC < 0.01) and high diversity gain (DG > 9.8). It also has very low channel capacity loss (CCL) which is found to be less than 0.2 Bit/s/Hz. The simulation results are compared with the measurement outcomes and found a good agreement between them.
