Design of a low profile UWB antenna for wearable applications

A low profile UWB antenna for wearable application is proposed. To accomplish the wideband characteristic, an elliptical patch, tapered feeding structure, and vias are adopted. The proposed antenna has a wide 10-dB return loss bandwidth of 5.6 GHz (2.9 GHz – 5.2 GHz and 7.1 GHz – 10.4 GHz). It can simultaneously cover low and high UWB bands (3.4 GHz – 4.8 GHz and 7.25 GHz – 10.25 GHz).
