description: The subject of the graduate qualification work is âInvestigation of the possibility of thermal stabilization of the characteristics of Reggia-Spencer phase shiftersâ.
This work is devoted to the study of the influence of climatic influences on the appearance of resonances in the operating frequency band of the Reggia-Spencer phase shifter.
The goal is to find the optimal parameters of the phase shifter design for its stable operation in a given frequency range at elevated and lowered temperatures relative to normal conditions (NC).
The Reggia-Spencer phase shifter was modeled using the HFSS program. It is revealed that the reasons for the movement of resonances in frequency are changes in the geometric dimensions of the structural parts of the phase shifter, as well as the influence of the dielectric permittivity of materials. With the orientation to the value of the temperature coefficient of permittivity, the relative permittivity parameter was adjusted for the materials included in the device design.
Measurements of a real phase shifter on a stand with a vector circuit analyzer were also performed which confirm the conclusions obtained during the simulation.
The technical result consists in expanding the working frequency band if the temperature coefficient of dielectric constant (TKÎµ) is approximately equal to â1500e-6 1/Â°Ð¡, which is only theoretically possible.
The result of the work is to provide information about the possible thermal stabilization of the phase shifter for JSC âMagnetonâ as recommendations as well as providing a working model for future calculations.
