In this paper the possibilities of realization of the waveguide elements in a structure of multilayered integrated circuits of centimeter and millimeter wave ranges are considered. It is shown that modern technologies of design and production of integrated circuits allow including three-dimensional elements, in particular cavity resonators on rectangular waveguides in its structure. Such technology has the name - SIW technology (Substrate Integrated Waveguide). As a result it is possible to unite advantages of rectangular waveguides, such as high Q-quality, small losses, large transmitting power, with advantages of microelectronic components - compactness, low cost, high flexibility of production. It is noted that for today there is a number of techniques, allowing to compute this structures, the part from them uses the principles of calculations of classical rectangular waveguides with certain assumptions, the part uses more bulky algorithms considering, partially or completely, real properties of geometry. Possibility of application in SIW structure not only rectangular waveguides, but also waveguides of complex cross-section which in classical all-metal execution possess a number of essential advantages, such as expansion of single-mode operating range, decrease wave impedance and mass-dimensional characteristics is considered. It is shown that application of the waveguides of complex cross-section allows to construct the devices based on the new physical principles, in particular, replacement rectangular waveguides by single-ridge waveguides in waveguide slot-antennas leads to reduction of the antennas area and expansion of scanning angles, and application of asymmetric single-ridge waveguides leads to elimination of secondary beams of the directivity pattern due to elimination of shift of longitudinal slots from the central waveguide axis. The solution of a problem of computer modeling of the waveguide and slot-antennas realized by SIW technology on asymmetric single-ridge waveguides is provided.
