Abstract :
A small footprint dielectric resonator antenna (DRA) for potential use in biomedical communication is presented. The antenna is designed to operate within the lower European ultrawideband (UWB) frequency band (3.4-5.0 GHz). The selected DRA geometry in combination with a lower permittivity material results in a reduction of antenna size with wide impedance bandwidth. The bandwidth is enhanced by removal of air region from the Dielectric resonator (DR) and high dielectric material is used to make the design more compact. The proposed DRA with good radiation characteristics offers a simulated bandwidth of 74% between 3.4 and 7.2 GHz for S11 <; -10 dB.
