Design of an Ultra-thin Compact Flexible Dual-Band Antenna for Wearable Applications

In this paper, a dual-band, flexible antenna is suggested. The low profile antenna, 35 × 20 mm

, is fed using the well known Co-Planar Waveguide (CPW) configuration, where it operates at 2.44 GHz and 5.8 GHz of the Industrial Scientific and Medical (ISM) radio band. By employing the flexible Rogers Ultralam 3850 as the antenna substrate, the proposed antenna exhibited high flexibility. Due to its compactness, flexibility and dual-band resonance at the ISM band, the antenna is highly chosen to be applied for wearable applications.
