Hypothesis
Can a half-mode substrate-integrated waveguide filter with Minkowski fractal improve performance for C-band applications?
Conclusion
The proposed filter achieves a compact size, low insertion loss, and good stopband performance for C-band applications.
Supporting Evidence
- The filter has a resonant frequency of 4.75 GHz and a 3 dB bandwidth of 770 MHz.
- Insertion loss measured at 1.05 dB and out-of-band rejection greater than 28 dB up to 8 GHz.
- The design integrates a Minkowski fractal for improved bandwidth and miniaturization.
Takeaway
This study created a small and efficient filter that helps improve satellite communication signals.
Methodology
The filter was designed using HFSS v19, fabricated on FR4, and tested for performance.
Limitations
The study may have slight deviations between simulated and measured results due to fabrication errors.
