The characteristics of a frequency doubler on a resonance microstrip structure with a thin magnetic film have been studied theoretically. The electrodynamic calculation of the structure was performed in the framework of the quasistatic approximation. Nonlinear response of the film magnetization was calculated by taking into account second-order terms in the Landau-Lifshitz equation. The amplitude-frequency characteristic of the microstrip resonator was calculated. It was shown that due to the use of the resonant design, high conversion efficiency of the input signal energy to the output signal at a double frequency was achieved. The optimum values of the external constant magnetic field magnitude and orientation, at which generation of the second harmonic peaked, were determined.

In this paper we study microstrips with rectangular and rounded edge cross sections. A hybrid quasistatic method is applied and the effective permittivity and the attenuation constant of the microstrip are found. Instead of the dielectric constant of the substrate an ideational one is used that depends on the geometry and the frequency. The attenuation constant for the rectangular microstrip was found to be in good agreement with values given in the literature. A microstrip with a rounded edge cross section has a smaller attenuation constant due to the conductor than that of a microstrip with a rectangular crosssection. Thus, a rounded edge microstrip is preferred because it will give an appreciable effect in reducing the ohmic losses of the line.
