Abstract

A Log Periodic Dielectric Resonator Antenna (LPDRA) for broadband applications is presented. In this paper, a broad bandwidth antenna is formed by application of log periodic technique to the series fed electromagnetically coupled rectangular overlaid dielectric resonator array. This Log Periodic DRA is simulated using a CST microwave studio suiteTM 2010. The simulated results show wider impedance bandwidth covering the frequency range of 6.4 GHz to 11.1 GHz with a VSWR less than 2 and radiation efficiency greater than 95 %. Its maximum gain is 7.2 dBi. Parametric studies of the antennas with CST microwave based design data and simulated results are presented here. The scaling factor of 1.05 has been chosen for this design.
