Compact Band-Pass Filter Made Using SIW Technology

Ahstract- The paper presents the possibility of reducing the weight and dimensions by bending the filter. In the course of the work, an electrodynamic analysis and synthesis of a third-order bandpass filter were carried out. These filters are made using SIW technology, which has gained great popularity due to the possibility of reducing the weight and size of the device compared to the classic rectangular waveguide. The amplitude frequency characteristics of the computer model and the manufactured filter are compared. The longitudinal size was reduced by 5 times compared to the prototype filter.
