Implementation and Experimental Characterization of Dual-Band Wearable Reflector Composed of AMC Structure for Wireless Communication

This paper presents an implementation of a dual-band wearable reflector composed of an artificial magnetic conductor (AMC) structure and its characterization through experimental measurement. The proposed wearable reflector, which is meant for wireless communications, comprises 3x3 AMC unit cells. Each unit cell comprises a square patch and a square ring patch with gaps placed in a concentrically organized pattern. An RT/Duroid® RO3003 dielectric substrate with a thickness of 0.5 mm is employed for the design and implementation. Meanwhile, a printed dipole antenna as an inseparable part of the wearable reflector is also deployed on the same dielectric substrate. This configuration, i.e., a printed dipole antenna and a wearable reflector, is expectable to operate at two different frequency bands or dual-band, covering the required frequencies of wireless communications while maintaining its compact size and simple configuration. Experimental characterization is applied to validate the proposed design, in which the results demonstrate the ability of configuration to work at two frequency responses, namely 2.45 GHz band, and 3.35 GHz band.
