PURPOSE: A dielectric resonator wideband antenna is provided to define design rule relating to the positioning of the dielectric resonator on its substrate which allows a widening of the passband without impairing its radiation. CONSTITUTION: A wideband antenna comprises a dielectric resonator(1) or DRA mounted on a substrate(2) with an earth plane. The resonator(1) is positioned at a distance x(xtop,xright) from at least one of the edges of the earth plane, x being chosen such that 0 <= x <= λdiel/2, with λdiel the wavelength defined in the dielectric of the resonator.
