摘要: This paper presents a new ultra-wideband (UWB) bandpass filter (BPF) with steeply slopes transition band using triangle-ring multi-mode stub-loaded resonator (MM-SLR). The consists of triangle ring for controlling the two transmission zeros at 2.8/ 11GHz and asymmetric tight coupled input/output (I/O) lines. There are five resonant modes generated in UWB passband including odd three even modes. by MM-SLR can effectively improve edge selectivity. attenuation slope lower higher edges proposed show 160 153dB/GHz, respectively. Experimental verification is provided good agreement has been found between simulation measurement.
