W-band waveguide bandpass filter with E-plane cut

W-band waveguide bandpass filter with E-plane cut.

In this paper, we present a design and measurements of a five-section bandpass filter with a passband from 96 to 106 GHz. The insertion loss is less than 1.4 dB in the passband, and the rejection is better than 40 dB in the range from 115 to 142 GHz. We use transmission line coupling theory based on Tchebyscheff's synthesis in order to provide an initial guess for the geometrical parameters of ...

Compact Dual-Band Bandpass Waveguide Filter with H-Plane Inserts

A novel compact dual-band bandpass waveguide filter is presented in this paper. H-plane metal inserts with complementary split-ring resonators are implemented as resonating elements in the standard (WR-90) rectangular waveguide. Design starts from the models of the waveguide resonators with two resonant frequencies (9 GHz and 11 GHz) using a single flat or folded metal insert. Further, folded i...

Design of Waveguide Bandpass Filter in the X-frequency Band

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, whe...

Novel Compact Wide-band Substrate Integrated Waveguide Bandpass Filter using Conductor Backed Coplanar Waveguide as Feed line for W-Band Communication Applications

In this paper a novel compact Substrate Integrated Waveguide (SIW) filter is proposed. A wideband band pass filter for microwave and millimeter-wave systems is investigated at 80 GHz center frequency with 10.5% fractional bandwidth. A Conductor backed coplanar waveguide is inserted in Substrate Integrated Waveguide (SIW) structure as transition to achieve sharper skirt characteristics. Simulate...
