  • Compact Microstrip Triple-Mode Bandpass Filters Using Dual-Stub-Loaded Spiral Resonators 

    Xu, K. D.; Li, M. Z.; Liu, Y. H.; Ai, J.; Bai, Y. C. (Společnost pro radioelektronické inženýrství, 2017-04)
    Two new microstrip triple-mode resonators loaded with T-shaped open stubs using axially and centrally symmetric spiral structures, respectively, are presented. Spiraled for circuit size reduction, these two half-wavelength ...
  • Super High-Selectivity Fifth-Order Bandpass Filter with Twelve Transmission Zeros 

    Cai, Y.-J.; Zhang, F.-Y.; Xu, K.-D.; Li, D.-H. (Společnost pro radioelektronické inženýrství, 2018-12)
    A fifth-order bandpass filter (BPF) with super high selectivity using three pairs of coupled lines and two open stubs is proposed. Twelve transmission zeros (TZs) from 0 to 2f_0 (f_0 denotes center frequency of the passband) ...
