| Sumario: | This paper presents a bandpass filter design based on a Substrate Integrated Waveguide (SIW) with resonant elements on both sides of the substrate. The proposed filter achieves a unique 0.5 GHz bandwidth centered at 6.54 GHz as well as demonstrates exceptional performance with a Voltage Standing Wave Ratio (VSWR) below 2, ensuring efficient power transmission. Additionally, the filter showcases a rejection level of more than 20 dB for out-of-band frequencies, highlighting its superior selectivity. The novelty of this work lies in the innovative combination of compact size, high frequency selectivity, and excellent VSWR performance, making it a standout solution for microwave and RF applications. By presenting comprehensive numerical and experimental results, including a detailed comparison with existing designs, this study underscores the significant advancements and advantages offered by the proposed filter in terms of size, frequency response, rejection level, and VSWR optimization. |
