WLAN Substrate Integrated Waveguide Filter with Novel Negative Coupling Structure

A fourth-degree Substrate Integrated Waveguide (SIW) crossed coupled band pass filter for WLAN band is designed by using a new negative coupling structure. It consists of two U shape microstrip lines on top and bottom planes with via holes at the center of them. This paper investigates the phase characteristics of negative and positive coupling structures and their effects. The design, fabricat...

Design of Narrowband Bandpass Filter on Coplanar Waveguide Using Spiral Slots

A configuration for a miniaturized band-pass filter on a coplanar waveguide (CPW) is proposed in this communication. Parametric studies conducted for various geometrical parameters suggest that the frequency response of the filter is strongly related to that of the spiral slots. A a series gap on the center conductor of the CPW changes the overall response of the device. For validation of these...

Substrate Integrated Waveguide Filters with Broadside-Coupled Complementary Split Ring Resonators

Four designs of substrate integrated waveguide (SIW) filter employing integrated broadside-coupled complementary split-ring resonators (BC-CSRR) are compared. By changing the orientation rings, four types of SIW unit cell are proposed and investigated and it is shown that, for one particular topology, two poles and two zeroes can be realised with a single unit cell. Bandpass filters based on th...
