Introduction. The actuality of the highefficient crystallike ingomogenities development is shown. Traditional microstrip (MS) and electromagnetic (EC) ingomogenities. Comparative effectiveness analysis of the traditional highimpedance microstrip and EC-inhomogeneities is conducted, the attention to the effectiveness limitations is noted. Comparative analysis of the traditional and three-dimensional EC-inhomogeneities effectiveness. It is shown that the three-dimensional inhomogeneities is more efficient wavereflector than traditional inhomogeneities. Three-dimensional EC-inhomogeneities with unrectilinear signal conductor. Mutual comparative effectiveness analysis of three-dimensional EC-inhomogeneities with different design implementation of the signal conductor is done. It is shown that three-dimensional EC-inhomogeneities effectiveness is large at about 2,4...3,1 and 1,4...1,8 times in comparison with MS- and typical two-dimensional EC-inhomogeneities, respectively. The wave deceleration in three-dimensional EC-inhomogeneity with zigzag signal conductor is more than 1.5, 2.1 and 2.6 times compared to MSL-inhomogeneity, typical two-dimensional EC-inhomogeneity and three-dimensional EC-inhomogeneity with a straight conductor, respectively. Conclusions. The considered three-dimensional EC- inhomogeneities with differing constructive and electric parameters, allow realizing highly effective microstrip devices in various constructive solutions.
