RÉSUMÉ

The results of experimental investigations of planar dielectric disk antennae with different dielectric substrates and radiating elements are represented. Geometric and electric parameters of antenna prototypes have been chosen in accordance with the theoretical calculations [1] to provide the conditions of the TM01 mode excitation in the electromagnetic structure under study. It has been determined that the use of substrates with different values of the permittivity gives rise to the change in the antenna patterns and the field intensity in their lobes. Moreover, the use of dielectric disks with high permittivity (εd = 90) provides an increase in the power radiated into the free space as well as a frequency band enhancement.
