Abstract :
A conical steerable dielectric resonator antenna is presented and analysed using an in-house developed FDTD simulator. A 30% impedance bandwidth is achieved with an average gain of 6.5% dB. Radiation patterns in the principal planes do not change significantly within the impedance bandwidth, presenting more than 18% dB front-to-back ratio in the azimuthal plane.
