N-Shape Dielectric Resonator Antenna for Wireless Communication

Roshni Gupta, Mangal Singh, Dipali Soren

Abstract


A new compact dielectric resonator antenna (DRA) for ultra-wideband (UWB) is presented and studied. This antenna is designed on FR4 substrate with dielectric constant of  and overall size of proposed DR antenna is 20×35 mm2. The dielectric resonator of N-shape is only of 5.12 mm thickness and has a very low permittivity constant (10.2). The simulated DR antenna operating from 4.4 to 11.7 GHz covers most of the existing wireless mobile standards. Radiation pattern is omni-directional and has a simulated gain value up to 4 dB and the total efficiency of antenna is 99%. The results are showing acceptable performance in terms of return loss, VSWR, radiation pattern and realized gain.
