In this paper, a miniaturized dual-bandpass filter based on dual-mode ring and coplanar waveguide (CPW) feeding is proposed. The filter is composed of two square dual-mode rings embedded with each other, and the inner ring adopts an arrow structure to realize capacitance loading to achieve miniaturization. Compared with the parallel coupling feeding structure, the CPW feeding method has design structure flexibility and better electrical performance. The designed dual-band filter is fabricated and measured to validate the present approach.
