description.abstractA Log Periodic dielectric resonator antenna (LPDRA)is proposed for K and Ka-band (18-40 GHz) applications. In this paper, by application of log periodic technique to the series fed electromagnetically coupled rectangular overlaid dielectric resonator array a new wide bandwidth antenna with flat conformal characteristics is formed. This LPDRA has been simulated using a CST microwave studio suiteTM 2010. The simulated results show the wider impedance bandwidth, covering the frequency range of 18–40 GHz with a VSWR less than 2 and radiation efficiency greater than 95%. Its maximum gain is 9.98 dBi at the central frequency 28 GHz. 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.en
