Zusammenfassung:A miniaturized square resonator bandpass filter with circular stubs is designed, fabricated, and characterized. Analytical calculations were carried out to determine the critical filter parameters and the design was optimized using a 3D electromagnetic finite-element solver. The measured results were in good agreement with the designed results. The pro-posed filter exhibits significant improvement in bandwidth compared to the conventional square resonator bandpass filters.
