SUMMARY In this paper, a compact ultra-wideband bandpass filter (UWB-BPF) using pseudo-interdigital stepped-impedance resonators (PIDT-SIRs) is designed and implemented on a commercial printed circuit board (PCB) of RT/Duroid 5880 substrate. The first two resonant modes of the SIR are coupled together and they are applied to create a wide pass-band. The(More)
SUMMARY This paper proposes a parallel coupled microstrip band-pass filter (BPF) with ring Electromagnetic Bandgap (EBG) cells on the middle layer for spurious suppression. The ring EBG cells of the middle layer add a good stopband-rejection mode to the second harmonics of the parallel coupled microstrip BPF with suppression of over −50 dB, without(More)
An experimental design utilizing artificial neural networks (ANNs), the Taguchi method, and the genetic algorithm (GA) is proposed to obtain optimal processing parameters for cathode arc plasma deposition of ZnO thin films on a glass substrate. The Taguchi method's orthogonal array is used to minimize the number of required experiments and to gather the(More)
—In this paper, we propose a novel approach for designing planar dual-band bandpass filter on a novel feed scheme. While we design this filter, the novel feed scheme is used to generate two passbands at 1.8 GHz and 2.4 GHz for global system for mobile communications (GSM) and wireless local area network (WLAN). Novel feeding structures are introduced to(More)
This research presents an assessment of dielectric properties for the microwave phantom production (MPP). The presented MPP was constructed by mixing organic compounds and inorganic compounds, which having particular dielectric properties. In addition, the fabricated MPP was analyzed to evaluate the relative electromagnetic properties based on the basic(More)
