Аннотация: The diplexers based on 2D electromagnetic crystal are investigated with the help of the numerical electrodynamic analysis of 3D models. The input half-wave resonator has rolled up strip conductor in the claimed microstrip designs tuned with nearly adjacent bandwidths. It allows to coordinate channels rather easily. Such resonator in the first two-channel device at the same time interacts with pair of quarter-wave resonators having strip conductors in the form of the Russian letter «Π». In the second two-channel device it interacts similarly, with pair of resonators with strip conductors in the form of a letter «III». Build-up of number of periodically located rectangular portions of strip conductors in adjacent resonators allows to increase in proportion number of the resonances participating in formation of both low-frequency, and high-frequency bandwidths. At the same time in amplitude-frequency characteristics of diplexers growth of the steepness of slopes of adjacent bandwidths and gain suppression of power at frequencies of stop bands are observed.
