Abstract	In this paper a design strategy to obtain low loss, small size dielectric antennas, by using very high dielectric constant materials is described. It is shown how by properly selecting the resonator shape and combining different resonant modes it is possible to design dielectric resonator antennas (DRA) with compact size and wide frequency coverage even at the cellular frequencies. Simple formulas are presented to illustrate the design procedure and allow a quick dimensioning of the antenna. Furthermore the paper describes techniques to enhance the response provided by the natural resonance frequencies of DRA, by adding parasitically coupled conducting strips, to enable multi-band operation. Results and examples are reported, showing the effectiveness of the proposed technique.
