Results of research of characteristics of printed-circuit vibrator radiators in plane infinite and finite phased arrays. When researching electrodynamical characteristics of the vibrator radiator, the charge method is used. To determine the direction diagram in the finite array, …


The radiator in question is a thin metallic plate, located on a single side of the dielectric substrate with dielectric permittivity ε and thickness z0. The opposite side of the substrate is metallized. Characteristics of radiators in the infinite array are studied in the excitation mode, when the voltage in the vibrator gap is constant modulus and characterized by ramp phase from radiator to radiator.

In section of “Publications-Archive” the “Mathematical modeling of microstrip oscillators in layered media” archival article is published. Author: V. V. Chebyshev.


In the article was a study of mathematical modeling of microstrip oscillators with a substrate in the form of plane layered media based on the use of integral and integro–differential equations of the first kind; there was provided substantiation and the basics of building the algorithms of a numerical solution to the equations; examples of the numerical study of the equations for oscillators and layered media with varied topology were given; the case of microstrip oscillators with …
