A slotted circular patch resonator is proposed to design a dual-mode dual-band bandpass filter in this work. Three sets of slots are etched into a circular patch. First, four arc-oriented slots are etched to lower the TM01 mode resonant frequency. Then, four radial-oriented slots are etched from the...
