  • Abstract
    This paper proposes a compact planar dual-band bandpass Alter (DBPF). The proposed DBPF employs a resonator comprising a combination of spiral and stepped-impedance structures in order to reduce the size of the DBPF. The feature of this filter is that these structures are placed close together to achieve a compact configuration. A 2.1/3.6 GHz superconducting planar bandpass filter is fabricated to investigate experimentally dual-band operation.
