In this paper a wideband half-split multilayer cylindrical dielectric resonator antenna (MCDRA) fed through coaxial probe is developed and discussed. The concept of multi layers is introduced in half-split dielectric resonator antenna for getting wide bandwidth. The design parameters of an antenna such as arrangement of dielectric layers, probe height and DR aspect ratio are investigated. The proposed multilayer cylindrical dielectric resonator antenna is excited with TM21δ mode. The proposed structure provides ~60% impedance bandwidth for input reflection coefficient (S11) below -10 dB with total gain of 6.09 dB.
