Abstract

A dual-band wearable antenna operating at 2.45 GHz and 5.80 GHz with compact Artificial Magnetic Conductor (AMC) plane is proposed in this paper. The design is based on a U-shaped printed monopole antenna operating in the Industrial, Science, Medical (ISM) bands, and it is integrated with a square looped AMC plane which can reduce the overall size of the antenna system and realize miniaturization. The U-shaped monopole antenna is miniaturized by folding its arms, and its resonant frequency can be tuned easily by adjusting the length of two branches. The AMC unit, which is composed of concentric square double rings, realizes dual-band resonance. Meanwhile, a crossed patch is loaded into the inner ring to increase the electromagnetic coupling and reduce the resonance frequency of the two rings, thus miniaturizing the AMC unit. Therefore, the total size of the AMC plane which contains 3×3 elements is only 59.1 mm × 59.1 mm. Specific Absorption Rate (SAR) is examined by loading a three-layer human body tissue under the AMC antenna, and the simulation results show that SAR value is only 0.018 W/kg, which is far below the Institute of Electrical and Electronics Engineer (IEEE) standard. Finally, a prototype of the proposed antenna was fabricated and tested, and the experimental results agree well with the simulation responses.
