“…Both designs make use of a high-permittivity substrate and superstrate and slotted ground plane. In contrast to the Planar Inverted-F Antenna (PIFA) [53], the antenna [52] does not include a shorting pin and thus is not a PIFA. The sizes of the antennas [52] and [53] are 7⨯6.5⨯0.377 mm 3 In the works [54] and [55], the authors have focused on improving the impedance bandwidth of dual-band PIFA.…”

This paper presents a triple-band open-ring high-gain high-efficiency antenna for 2.45/3.0/3.45 GHz wearable applications. The proposed antenna operates at 2.45 GHz for Industrial, Specific, and Medical (ISM) applications, 3.0 GHz for military applications, and 3.45 GHz for Worldwide Interoperability for Microwave Access (WiMAX) applications. The proposed triple-band antenna has excellent features for offbody communication, which has directional radiation pattern, high gain, high efficiency, low-specific absorption rate (SAR), and comfortability for wearers. In order to attain these features, the antenna structure consists of two substrates, a rigid substrate and a textile substrate. Two open-ring radiators and a 1 by 2 power divider feeding network are printed on a low-loss rigid substrate. In addition, a square conductive textile is adhered on the backside of the textile substrate. The open-ring radiator generates triple-band at 2.45, 3.0, and 3.45 GHz, in which the inner open-ring excites two resonant modes at high frequencies of 3.0 and 3.45 GHz. The outer open-ring excites a single resonant mode at a low frequency of 2.45 GHz. The outer annular ring is shorted to the ground plane by a shorting pin to miniaturize the antenna size and additionally maintain antenna stability. The conductive textile works as a full-ground plane or protective shield to reduce the electromagnetic waves toward the human body. Therefore, the SARs are significantly minimized. The compatibility of the proposed antenna for off-body communication is verified by measuring the antenna performance in free-space and on phantom/human bodies. The simulated and measured results show very good agreement.INDEX TERMS off-body, SAR, triple-band, flexible substrate, wearable antenna.

A quad-element multiple-input multiple-output (MIMO) antenna is designed at 433 MHz Industrial, Scientific, and Medical (ISM) band, to increase the transmission datarate and minimize the multipath fading. The proposed MIMO antenna consists of semi-circular meandered radiators with a shared ground. It is designed and optimized inside an implantable medical device (IMD) in a human head model. The antenna's results show a 10-dB fractional bandwidth (FBW) of 38.26% (355-523 MHz) with a peak realized gain of -28.3 dBi. A high isolation (> 32.6 dB) between MIMO elements is obtained using a central metallic via. Specific absorption rate (SAR) and link budget are analyzed to validate the effectiveness of this antenna. The 4 × 4 MIMO channel parameters are calculated and validated. Furthermore, this antenna provides a channel capacity of 19.9 bps/Hz which is about three times higher than the singleinput single-output (SISO) configuration of ≈5.89 bps/Hz. Hence, this MIMO configuration is a promising candidate for high-datarate head implants.
