Design of Substrate Integrated Waveguide Bandpass Filter for X Band Applications
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 7
Abstract
This paper presents the design of substrate Integrated waveguide (SIW) bandpass filter for the X band (8 GHz to 12 GHz) applications. Substrate integrated waveguide is quite popular in filter design due to its high performance.The bandpass filter is used to receive the desired band of frequency and to reject the frequency which is out of interest. In this paper, we used the U slotted structure to improve the stopband performance of the filter at the upper band of frequencies. Taper section is provided to avoid the sharp transition from the feedline to the SIW structure which improves the S11 performance of the filter. The simulated results are obtained from the CST software. The results show that the designed filter gives better performance and it is well suitable for the X band applications.
