This paper is devoted to the development and research of antennas based on cylindrical and rectangular dielectric resonators. The technique that combines analytical calculation of radiating elements geometry and electrodynamic analysis of antennas in general, using modern software tools for modeling microwave devic es is presented. Special attention is paid to the optimization of such design parameters as resonators height and exciting probes length. The influence of these parameters on radiation efficiency and the bandwidth of matching radiating structure with a feeder is shown, which made it possible to solve the problem of antenna synthesis by optimizing their designs in accordance with the requirements of technical specification. The use of dielectric resonators makes it possible to create compact and efficient antennas suitable for wireless sys tems, radars and satellite communication systems.
Key words: : antenna, dielectric resonator, resonant frequency, radiation pattern, gain, radiating struc ture, electrodynamic modeling.
