Abstract：

In　this　paper,　a　compact,　high-selectivity　and　wideband　high-temperature　superconducting　(HTS)　bandpass　filter　(BPF)　with　a　narrow　notched-band　is　reported.　This　wideband　BPF　is　realized　using　a　multi-mode　resonator　(MMR)　with　two　different　T-shaped　stubs.　For　improving　the　filter　selectivity,　multiple　transmission　zeros,　which　are　located　close　to　either　side　of　the　wide　passband,　were　created　by　loaded　stubs　and　source-load　coupling　technique.　Moreover,　two　identical　λ/2　spiral　resonators　are　inserted　into　the　filter　to　create　a　narrow　notched-band.　Finally,　simulation　results　of　the　proposed　filter　show　good　performances　and　compact　size.　©　2018　IEEE.
