摘要：
The paper examines the characteristics of the miniature sensor of weak magnetic fields on the resonant microstrip structure with a thin ferromagnetic film. The authors calculated the frequency response of irregular microstrip resonator containing anisotropic magnetic film in quasi-static approximation. The resonator is connected to transmission lines via coupling capacities. The authors determined the optimal directional angles of the constant magnetic displacement field ensuring maximum sensitivity of the sensor. They examined the impact of angular and amplitude dispersion of uniaxial magnetic anisotropy of thin film upon the sensor characteristics. The regularities determined in this research qualitatively agree with the experimental results.
