N2 - A wideband cylindrical dielectric resonator antenna (CDRA)-loaded with an annular column, namely the LCDRA, is proposed and analyzed. The antenna comprises two components-An inner cylindrical dielectric and a loaded concentric column dielectric. The proposed antenna is centrally fed by a coaxial probe, and has a low profile of 0.175 γ0 (γ0 is the wavelength of the center frequency). Four conical radiation pattern modes (TM01δ, TM02δ, TM03δ, and TM04δ modes) are excited and merged, providing an impedance bandwidth of 56% (3.14-5.56 GHz). A prototype of the proposed antenna is built and tested. Good agreement between the simulated and measured results, including the reflection coefficient and radiation patterns, is achieved.
