A wearable antenna that works on two different frequencies is proposed in this paper. A smaller circular patch antenna based on previous research articles is proposed. One of the major attractions of a wearable antenna is its smaller size. The proposed antenna structure is designed by adopting various miniaturization techniques and it resembles a simple cuff button. The radiating structure is square shaped with fillet edges and has a circular-shaped patch. The ground plane extends to the entire plane and therefore, back reflections can be avoided. The substrate used is a Polytetrafluoroethylene PTFE Taconic ceramic substrate whose dielectric permittivity is 10. The substrate has a thickness of 3.18 mm. The substrate is originally rectangular shaped and the shape of a cuff button is achieved by side filleting. The structure is rigid enough to be used as a wearable antenna. The proposed wearable antenna is designed for 2.4 GHz and 5.6 GHz with an omni-directional pattern required for transmission with other wearable devices located across the body.
