Compact Three-layer Band-pass Filter Based on SIW-technology

The results of electrodynamic analysis and a band pass filter synthesis are presented in the article. The filer is developed using SIW technology, and a three-layer filter is made by bending the original filter three times. The main advantage is the reduction in the weight and size of the filters while maintaining the same resonant characteristics and bandwidth. Both filters configurations, their characteristics and dimensions are shown. The computer simulation was carried out using the CST Microwave Studio software package.
