A recent paper [1] has introduced a new class of dielectric resonator antennas (DRAs), the so-called supershaped DRAs (S-DRAs).

Abstract
A recent paper [1] has introduced a new class of dielectric resonator antennas (DRAs), the so-called supershaped DRAs (S-DRAs). This class of radiators took its name from the mathematical formula, known in literature as superformula (see [1] and references therein), that defines the geometry of the base of the dielectric prism acting as dielectric resonator (DR). S-DRAs feature wideband matching characteristics (with relative bandwidths exceeding 50%) and broadside radiation. Moreover, the radiation pattern of this family of DRAs can be varied by changing the DR shape such to become broad and rather stable over large frequency ranges. All these features, combined with the possibility of manufacturing S-DRAs in an inexpensive manner, suggest a possible application of these components in the realm of indoor communication. More specifically, such antennas could be used as access points for wireless local area networks supporting ultra wide band application. © 2010 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
