The aim of this work is the development of a cylindrical dielectric resonator antenna with multimodal operation. In order to use modes with different radiation patterns, the field distributions were investigated. Using a feeding solution with the resonator placed asymmetrically above a wide microstrip feeding line, we managed to excite and identify 17 operating modes in the 1.8-4.5 GHz frequency band. In dissimilarity with the symmetric configuration, the proposed feeding allows excitation of new modes, which exhibit a magnetic dipole radiation pattern. The new added modes enhance the antenna pattern diversity and increase the antenna capacity to mitigate the multipath effects..
