MICROMECHANICALLY RECONFIGURABLE RESONANCE MICROWAVE ELEMENTS BASED ON THE COPLANAR AND SLOT LINES. The object of research is micromechanically tunable resonant elements based on coplanar lines and slot lines. This work aims to determine the principles of micromechanical tuning of microwave resonant elements based on coplanar and slot lines and to study the effect of geometric and electrophysical parameters of resonator structures on their frequency characteristics. Research methods include numerical methods for solving electrodynamics problems for the calculation of the electromagnetic field, experimental measurements of the scattering matrix elements. Emphasis is placed on the tunable filters based on the coplanar line with defected ground structure. Such filters have a wide scope and many frequency tuning options such as electrical, magnetic, optical, etc. However, the micromechanical tuning method has not been sufficiently investigated in the case of using coplanar lines with defected ground structure. Methods for micromechanical tuning of coplanar and slot lines effective parameters are investigated in the work. Methods for their effective parameters calculation are developed. Designs of micromechanically tunable filters based on the coplanar line with the defected ground structure are proposed. The influence of geometric and electrophysical parameters on the filter tuning range and tuning sensitivity to micro displacements is investigated. The proposed frequency tuning method provides continuous frequency tuning, a wide tuning range, up to 40% and does not add any additional loss or distortion to the filter frequency characteristics. The required displacements for tuning are tens of micrometers, which allows the use of micromechanical electrical systems or piezoelectric motors as control elements.
