چکیده
This paper presents a quasi-elliptic filter (QEF) with arbitrary termination impedances (ATI). The proposed QEF is designed by adding cross-coupling between the first and last resonators of an ATI bandpass (BPF) Chebyshev response. QEFs can be in even-order location pair transmission zeros (TZs) controllable. To prove validity design, fourth-order were implemented on single-layer substrate-integrated waveguide (SIW) cavity at center frequency (<i>f</i><sub>0</sub>) 10 GHz TZs ± 1.4 GHz. These SIW improve selectivity effectively suppress out-of-band signal high power handling. measured maximum insertion loss (|<i>S</i><sub>21</sub>|) minimum return (|<i>S</i><sub>11</sub>|) unequal real-to-real are 0.93 dB 17.4 dB, respectively, passband. Similarly, |<i>S</i><sub>21</sub>| |S<i>S</i><sub>11</sub>| complex-to-real 1.2 18 respectively.yer (

متن کاملA 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.

متن کاملDual-Band Evanescent-Mode Substrate Integrated Waveguide Band-pass Filter for WLAN Applications
A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...
