ABSTRACT: 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 proposed filter exhibits significant improvement in
bandwidth compared to the conventional square resonator bandpass filters.
