U ovom radu smo definirali što je DRA, kako se dizajnira, što predstavlja i kako izračunati rezonantnu frekvenciju. Cilj ovoga rada je proučiti kako se ponaša DRA, u ovisnosti dimenzija, oblika, te dielektricne konstante.This paper present the dielectric rezonator antenaa (DRA), what does it mean, how to design it, how do we calculate the resonant frequency. While designingDRA with the toolkit HFSS, the main goal was to present how to design a DRA, and to see how to achieve specific needs by manipulating the dielectric constant or the dimensions of the DRA
