Wearable triple band WLAN antenna on leather belt

In this work, a compact triple band wearable antenna for Wi-Fi applications, specifically designed to be fully integrated in a leather-made belt, is simulated, constructed and measured. The layout of the radiating element is constructed from an array of circular patches, and the ground plane contains several defected structures, known in literature as DGS. The antenna project has been chosen and optimized under both electromagnetic and manufacturing point of view to be fully integrated within a leather belt, placed on the waist of the human body. For these reasons, the same leather material properties have been used in simulation of the substrate material, and conductive copper foil for the design of the radiating parts and the substrate.
