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 backward 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.read more
