Abstract
The design of a singleelement antenna, where cylindrical dielectric resonator, which is located orthogonally relative to feeding microstrip line, is used as radiating element, is described. There have been performed the numerical analysis of it and defined the functions approximating its directivity patterns. The schemes of feeding arrays of dielectric resonators for narrowing directivity patterns in E- and H-planes are proposed. The numerical analysis of antenna array 4x4 elements was performed and comparison of gained directivity patterns with ones calculated from analytical expressions was made. The graph of dependence of width of the main lobe in E- and H-planes for arrays of dielectric resonators versus the number of resonators in corresponding planes was plotted.
