Calcium oxide (CaO) powders were prepared from eggshell’s calcium carbonate (CaCO3) obtained from control-range system (a supermarket) and free-range system (opened natural farm) hens. The CaO powders were sieved at 140 µm, put into porcelain cruc

This paper proposes parallel-coupled stepped impedance resonators (SIRs) used for wideband bandpass fllters with reduced size and improved spurious response suppression in out-of-band. The fllter design concept is demonstrated by both two- and four-p
