Small size wearable button antenna

A novel small size wearable antenna for WLAN applications is proposed in this paper. The antenna structure is based on a previous development and achieves lower size by implementing different miniaturization techniques. The radiating structure has the shape and dimensions of a standard denim jeans button and is made up of a button shaped cylindrical structure and a top metal disc connected to the ground plane. The antenna is also filled by a dielectric material and an extra shorting via connects the two top parallel plates. The structure and dimensions achieved are those of a standard metal button with greater deal of camouflage and rigidness than previous wearable antenna developments. The proposed wearable antenna is designed for 2.4 GHz and 5 GHz with an omni-directional pattern required for transmission with other wearable devices located across the body.
