Abstract :
In order to maneuver over the ultra wideband range, several structures have been investigated with increased impedance bandwidth. In this context a three stacked conical ring dielectric resonator antenna has been proposed to operate beyond the ultra wideband range. The proposed antenna offers a fractional bandwidth of 161% with a monopole type radiation pattern. The enhanced bandwidth is due to the resonance of the monopole antenna at about its each wavelength for which the stacked conical resonators are highly indispensable.
