Abstract

In this letter, the miniaturized bandstop filter with lumped capacitor element is presented. The resonator is based on a stopband characteristic of U‐shaped defected ground structure (DGS) section. Lumped capacitor element is embedded into DGS section without altering the geometry. The resonant frequency of DGS section is significantly lowered in accordance with increase of capacitor value. The DGS section with different capacitance values is designed and fabricated. From the measured results, size reduction over 60% is achieved by this method. © 2009 Wiley Periodicals, Inc.

## Abstract In this article, we proposed a new compact defected ground structure (DGS) band‐stop filter with broad passband and low insertion loss in the stop‐band. The philosophy of the structure behind this new microstrip band‐stop filter is simple as it is composed of a pair of octagonal DGS‐slo

## Abstract This paper presents the application of an iterative method for fast computation of microstrip interdigital capacitor (IDC) and a quasi‐lumped miniaturized filter. The use of a 2D‐FFT algorithm allows simplifications in the calculation process leading to accurate results obtained 20 time

## Abstract This letter proposes a new miniaturized wideband coupled‐line microstrip balun and its design procedure based on an original finding. This finding suggests that the coupled‐line microstrip balun can be realized by using a much smaller high‐pass ground defect instead of a bandstop ground

## Abstract A new I‐shaped defected ground structure (DGS) is used to relocate the microstrip resonator's second harmonic at the proximity of the fundamental passband to realize dual‐band bandpass filter. This DGS is validated by a compact dual‐band bandpass filter at 1.44 and 2.35 GHz with simulat
