Abstract

This letter presents the design of a wearable dual-band patch antenna for operating in the GSM-900 and 1800 bands. The proposed polygon patch antenna comprises a circular slot and vertical slits embedded on jeans substrate. This structure provides two paths for currents, making it viable for dual bands. The effect of patch length, slot radius, and slit length on the overall antenna performance is analyzed by performing a comprehensive parametric study. Further bending, crumpling, wetness, and on-body measurements have been performed to validate the structure. Specific absorption rate (SAR) values ranging between 0.00039-0.0035 W/Kg have been obtained for two different analyses.
