Waveguide Bandpass Filter Using Artificial Magnetic Conductor

Miniaturized Microstrip Bandpass Filter Using Coupled Metamaterial Resonators

A compact microstrip band pass filter using metamaterial resonators is proposed and implemented, aiming at high level of miniaturization, low cost and ease of fabrication. Some considerations in order to improve and control the coupling coefficients between resonators are exposed. The magnetic and electric character of the coupling coefficient is analyzed in detail. The proposed filter has narr...

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...

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...
