Design of Waveguide Bandpass Filter in the X-frequency Band
نویسندگان
چکیده
How to design a broad bandpass filter in the X-frequency range? The design procedure is developed from synthesis to electromagnetic simulation. The filter to be designed is implemented in waveguide technology with inductive irises coupling sections. So as to evaluate equivalent susceptance of iris aperture, two methods were used: the first one is based on classical mode matching techniques, whereas the second uses electromagnetic-based equivalent circuit. The susceptance values ensued from these methods were then compared. Validations for both methods were carried out using Ansoft-HFSS electromagnetic simulations and measurements.

A Compact Wide Bandpass Filter based on Substrate Integrated Waveguide (SIW) Structure
In this pare, a wideband three-order bandpass filter (BPF) is proposed. The proposed wideband filter is designed using the substrate integrated waveguide (SIW) structure by loading T-shape slots. A BPF with two resonators is formed by etching T-shape slots with different size on the top metal plane of the SIW structure. The filter is investigated with the theory of coupled resonator circuits. T...

A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...

In this paper, chiral E-shaped resonators are used in a waveguide. Direction of EM wave and position of resonators for effective excitation is studied and various resonances of E-shaped resonators are determined. As a consequence an analytical equivalent circuit model is proposed. Finally, an array of these resonators is used to realize a wide reject band. The resulted band stop filter performa...
