Abstract

A low profile UWB antenna with conical radiation for on-body communications is proposed. The antenna has overall dimensions of 64 mm × 64 mm × 6 mm (0.64 λ 0 × 0.64 λ 0 × 0.06 λ 0 at 3 GHz) in the Impulse Radio UWB (3.1 GHz – 10.6 GHz) band. The proposed antenna is composed of a mono-cone and a TM41 higher-order mode shorted ring patch. The simulated results show that the proposed antenna obtains monopole-like radiation performances in the whole operating frequency band. The radiation pattern of the proposed antenna on the phantom is similar to that in free space so that the on-body WBAN application can be feasible.
