Design, Simulation and Fabrication of Ferrite Phase Shifter Waveguide in Frequency Band X

Document Type : Original Article

Abstract

In this paper, the design and fabrication of a non-reciprocal phase shifter with high power handling capability is considered in the frequency of 9.4 GHz. In the design procedure, the effect of ferrite parameters such as location, width, and DC magnetic bias over phase shift value and insertion loss is outlined. By considering various parameters, the optimum design to obtain suitable phase shift is chosen. As regards impossibility of theoretical analysis of such structures, the HFSS simulator is used for calculation and optimization of the phase shifter. To ensure HFSS results, the structure is also simulated using the CST simulator and obtained results of two simulators are compared together. The final phase shifter consists of standard waveguide WR-112 and four ferrite slabs where connected to the wide wall of waveguide with dimension of 2mm×5mm×30mm. The measured results show that the 90° phase shift and insertion loss about 0.15 dB are obtained in frequency of 9.4 GHz. The measurement results have a very good agreement with simulation results.
