Design & Simulation of Dielectric Resonator Antenna for Millimeter Applications

This paper presents the design and simulation of broadband Dielectric Resonator antenna using
HighFrequency Structure Simulator (HFSS). This paper investigate stacked cylindrical DRA,s placed on
concentricannular rings .These hybrid nature of structure is operating under controlled electric fields and
magneticfields. Higher gain has been reported in proposed work when electric bias is given , under magnetic
biasbandwidth of the antenna is enhanced by making little bit compromise on the Gain. Frequency shift has
also been notice during magnetic and electric bias condition .This can be wisely used for getting
reconfigurability.
