The method of closed form construction of functions of surface impedance of microstrip structures is proposed. Results of calculations are in good agreement with published date.
Probing tolerance limitings on the geometrical sizes constructions of the microstrip filters is carried out. Also, view of approximation amplitude-frequency characteristics, providing the necessary characteristics of the filter take into account. The synthesis of filters is fulfilled on the basis filters- prototypes of the lower frequencies. Calculation of tolerances is made with usage of interval...
Considered in this paper is wavelets application in order to increase the efficiency of integral equations solution. Wire antennas with fractal structure have been calculated and the expediency of application of such basis functions is shown. The accuracy of the results obtained is estimated
Quasi-dynamic closed expressions for calculation of the dispersion dependences of the microstrip line input impedance are proposed. These expressions provide high accuracy calculation of the input impedance on the initial section of the axis in the area of weak dispersion of the microstrip parameters and reproduce the tendency of change of dispersion curves with increasing frequency. For the analysis...
