Abstract

A novel quarter substrate integrated waveguide resonator (QSIWR) with an etched elliptic defected structure (EDS) to reduce its resonant frequency employs electric coupling in the main path and magnetic coupling in the cross-coupled path to realize a miniature cross-coupled bandpass filter (BPF) with a size reduction greater than 88 percent. The filter possesses a transmission zero (TZ) in the upper stopband, which improves selectivity. [ABSTRACT FROM AUTHOR]

Abstract

The article focuses on the use of quarter substrate integrated waveguide resonator (QSIWR) and a fractal shaped defected structure (FDS) in designing substrate integrated waveguide (SIW) bandpass filters. It states that QSIWR and FDS are used because of various benefits including simple structure, extra transmission zero and compact size. It further presents various figures explaining the working of QSIWR.
