“…A deployable wearable antenna is modeled on a body with a thickness of skin=2.00mm, fat=4.00mm, and muscle=10.0mm producing a maximum specificabsorption rate of 0.512 W/Kg at 2.45GHz [31]. A breastcancer antenna is capable of detecting tumors which is traceable between a bandwidth of 8.50GHz-10.50GHz [32], [34]. A detailed investigation of SAR and thermal effects is studied by using patch-antenna when deployed on the body and also checking on the fabric-cotton wearable applications with antenna providing resonance at 1.80GHz, 2.40GHz, and 5.00GHz and 8.90GHz.…”

In this endeavor, miniaturized quad-port MIMOMB (multiple-input-multiple-output multiband) antenna with an overall area of 400 mm 2 offering wider-impedance-bandwidth of 8.31GHz-36.14GHz is reported which covers multiple bands including X-band (8.00-12.0 GHz), Ku-band (12.0-18.0 GHz), Kband (18.0-27.0 GHz), partial GHz) is reported for wideband infrastructure. The proposed antenna radiating EM energy is printed on very thin Rogers RTDuroid5880 substrate with thickness 0.254mm. The radiating EM wave patch consists of hexagonal geometry which is etched with a circular-rectangular slot and partialground etched by a beveled shape patch for matching of impedance. The conformal capability of the proposed antenna is verified by S-for single-port, dual-port, and proposed four-port antenna. The time-domain analysis confirms the faithful reception of transmitted signals in far-field regions. The diversity performance including ECCMB, DGMB, TARCMB, CCLMB, and MEGMB is below permissible standard values with a maximum peak gain of 7.17dBi with stable 2-D radiation patterns in principal planes. The Specific-Absorption-RateMB (SAR) analysis is carried out at different operating frequencies in Microwave-Millimeter wave bands with SAR ≤1.60W/Kg in human phantom tissue and makes it suitable for on-body wireless applications.

This paper presents a compact 5G wideband antenna designed for body-centric networks (BCN. The single element antenna design includes a simple T-shaped radiator patch with ring shaped ground plane and transformer impedance feedline. First, the antenna was simulated in free-space, and its resonant frequency is found to be 27 GHz, falling within 5G’s n261 band. The proposed single radiator antenna has a size of 23.375 mm3, and it offers a wide impedance bandwidth of 2.0 GHz (26–28 GHz). Parametric studies demonstrated that by increasing the length of slots in patch, the antenna frequency can be reduced further. Single radiator antenna is used as 8-element MIMO structure. Parallel adjacent antenna in X-direction has minimal coupling effect, whereas antenna placed in Y-direction has high coupling effect. Thus, coupling is reduced by etching a wall of slots in ground plane. It alters the surface current interference in Y-direction and limits the coupling effect. The antenna is investigated to use in body area network applications. To evaluate its on-body performance, an equivalent body model is virtually developed. The on-body performance is assessed by placing the antenna in close proximity to body model. Stable and robust performance is achieved for the on-body operation. At the resonant point, the antenna exhibits a reflection coefficient of -30 dB (free space) and -40 dB (on-body), high isolation of above 20 dB between adjacent radiators and above 30 dB for other radiators. Antenna has stable performance for different body tissues and on the non-planar structures. Bidirectional radiation pattern with gain of 2.53 dB and broadside type orientations with gain of 4.64 dB are achieved for free space and on body operations respectively. low specific absorption rate makes antenna safe for health care devices. Further, diversity performance is measured in terms of envelope correlation coefficient (ECC), and diversity gain (DG). Maximum Value of ECC is 0.005 and minimum value DG is 9.97 at 27 GHz which confirms the excellence of antenna for MIMO applications.
