A wide stopband and high isolation balanced diplexer (BD) using asymmetric hairpin ring resonator (A-HRR) is presented in this paper. By virtue of the flexibility AHRR, removed differential-mode (DM) spurious harmonics common-mode (CM) frequencies A-HRR are analytically illustrated. And applied to design proposed BD. Due complexity inaccuracy conventional method BD, grey wolf algorithm (GWA) adopted optimize physical parameters BD circuit reach desired performance rapidly accurately....
A balanced ultrawideband (UWB) high-temperature superconducting (HTS) bandpass filter (BPF) with miniaturized size and high selectivity is proposed based on a four-cell via-free CRLH-TL. The differential-mode (DM) common-mode (CM) equivalent circuit models are established. DM operates as an eighth-order BPF three transmission zeroes the out-band while CM can get suppression. gray wolf algorithm (GWA) used to derive element values in then optimize physical parameters layout. Finally,...
Abstract In this paper, a compact quad-channel filtering diplexer using meander hairpin ring resonators (M-HRR) aided by grey wolf algorithm (GWA) is proposed. To realize size of the multi-channel diplexer, form meander-line structure applied to resonator for miniaturization proposed diplexer. Then, coupling topology 0° feeding structure, transmission zero generated between two resonant frequencies M-HRR improve band-edge selectivity and band-to-band isolation address problematic challenge...
In this paper, a 30 dB broadband microstrip directional coupler is designed by using discrete coding type coupling structure with co-simulation technique. Combined the proposed hybrid binary particle swarm genetic optimization algorithm (HBPSGOA) and carefully fitness function, can provide satisfactory flexibility excellent performance. For fixed design space, space firstly be encoded mapped to corresponding matrix, then optimal matrix searched HBPSGOA will used high directivity. The...
In this study, an on-chip mm-wave ultra-wideband (UWB) bandpass filter (BPF) is designed utilizing the hybrid whale grey wolf optimization (HWGWO) algorithm. The BPF performance evaluated at two distinct temperatures: 300 K and 77 K. A comparative analysis of filter's frequency responses these temperatures performed. findings reveal improvement 0.12 dB in in-band insertion loss a shift operational by approximately 0.3 GHz compared to Additionally, HWGWO employed globally extract parameters...
