A wearable dual-band magneto-electric dipole antenna is proposed. Two U-shaped slots are introduced on a dipole and the resulting electric and magnetic resonances are combined with the aim to produce a dual band with wideband characteristics. The antenna is fabricated fully using textiles, except for the feeding connector. Simulations and measurements confirm the wide bandwidth and a low backwards radiation in both the lower and the upper band. The antenna is robust and not very sensitive to bending when worn by the user. The specific absorption rate is studied numerically and proven to be well below the European limit of 2 W/kg.

“…4 (c) -(e). It should be noted that unlike the antennas that are designed to operate in on-body [6] or off-body communications [7], the radiation patterns of the proposed antenna in the vicinity of the torso are not of interest, and are only presented to confirm that the maximum radiation is indeed at the desired direction, e.g. -x-direction.…”

“…The needed antennas should be wideband and unidirectional to obtain suitable image resolution and utilize the limited allowed microwave power, respectively. There are several antennas that are designed for medical diagnostic applications [6] - [9]. Owing to their simple structure and light weight, the end-fire planar antennas are among the most preferred ones for medical diagnostic systems [10] - [11].…”

A slot-loaded meandered loop antenna for congestive heart failure (CHF) detection system is presented. To meet the requirements for a CHF detection system, the antenna is designed to have a compact size, wideband at the ultra-high frequency band and unidirectional radiation. To that end, several techniques are applied to the main utilized structure, which is a conventional loop antenna. To lower the resonant frequency and enhance the directivity within a compact size, the loop is capacitively loaded using a pair of slots. To compensate for the effect of the capacitive coupling on the input impedance matching, an inductive reactance is added by meandering the loop's structure. With the applied modifications, the proposed antenna has a compact size of 0.21× 0.21 with respect to the wavelength at the lowest operating frequency. The realized dimension represents only a quarter of the size of its counterpart planar designs. The proposed antenna achieves a wide measured fractional bandwidth of 50 % (0.66 -1.1 GHz), 9 dB peak front to back ratio and 4.1 dBi gain. The antenna is then used as part of a CHF detection system that also includes a compact transceiver, scanning platform and laptop for control and processing. Using a suitable frequency-domain processing and imaging algorithm, the system successfully detects an early CHF in an artificial torso phantom.Index Terms-Loop antenna, dipole antenna, unidirectional antenna, congestive heart failure, pulmonary edema. 0018-926X (c)

“…Since a flat conformal structure with a large ground plane is required, patch antennas are usually chosen as the basis of wearable antenna designs [2][3][4][5][6][7][8][9]. To date, several designs involving slots and/or metamaterials have also been proposed to generate a dual-band behavior [10][11][12].…”

A low profile dual-band antenna based on the magneto-electric dipole concept is investigated on-body. An efficient space-utilization configuration of the conductive textiles and substrate layers ensured the compactness of the structure for on-body application. The two U slots in the dipole combine the electric and magnetic resonances to produce a dual band behavior and wideband characteristic in each band, as validated via simulations and measurements. Low backward radiations in both the lower and the upper bands are observed, rendering it insensitive to the coupling to the human body. To validate this, the antenna is first simulated in a bent configuration using a simplified, cylindrically-shaped human phantom and was found to be robust. It was then simulated on a detailed voxel model to assess its bent performance. Besides the slightly degraded reflection performance, the studied specific absorption rate (SAR) is proven to be well below the European limit of 2 W/kg.
