## Abstract In this article, several square openβloop resonators with transmission lines are proposed to design the optimized bandpass filters. A compact microstrip filter using an openβloop resonator was designed, fabricated and measured. At the center frequency f~0~ = 1.80 GHz, a 3βdB bandwidth o
