Abstract
Compact dual-band bandpass filters with stepped-impedance conductor-backed asymmetric coplanar waveguide resonators are proposed, and synthesis formulas are derived to facilitate the design. By using an asymmetric topology, two additional transmission zeros are obtained. To further improve the selectivity, an embedded coplanar waveguide resonator is proposed to achieve two independently controllable transmission zeros. Two dual-band bandpass filters are designed and fabricated. The measured results validate the proposed design.
