WebAug 19, 2024 · This article presents a wideband tunable balanced bandpass filter (BPF) with stable passband selectivity using optimized varactor-loaded half-guided wavelength stepped impedance resonator (SIR). By overall investigation, it can be found that the frequency-tuning range of the varactor-loaded SIR is not only controlled by the variation …
A propagation mode in a waveguide is one solution of the wave equations, or, in other words, the form of the wave. Due to the constraints of the boundary conditions, there are only limited frequencies and forms for the wave function which can propagate in the waveguide. The lowest frequency in which a certain mode can propagate is the cutoff frequency of that mode. The mode with the lowest cutoff frequency is the fundamental mode of the waveguide, and its cutoff freque… WebJan 13, 2024 · The higher FTBRs occur periodically about every half-guided wavelength (marked by the dotted vertical lines) with an overall increasing trend from 12 to 20 dB as the L air in the range from 1.0λ g to 3.0λ g.
