Abstract

An elliptical shape patch (ESP) antenna with inverted U-shaped slots is proposed and presented in this paper for on-body communication. A coplanar waveguide (CPW) feed is used as ground to produce impedance matching, and inverted U-shaped slots are used to produce the ultra-wideband (UWB). The proposed ESP antenna model covers UWB characteristics in free space, and it is observed at 3 to 10.7 GHz. When it is implanted on flat tissue model of human body, the bandwidth is 2.2 to 10.8 GHz. The SAR values of 1.26 W/kg and 1.58 W/kg are observed on-body at 4.9 GHz and 7.3 GHz operating frequencies, respectively. The results with respect to radiation pattern, gain, reflection coefficient, surface current distribution are also presented.
