A New Defected Ground Structure for Different Microstrip Circuit Applications
In this paper, a microstrip transmission line combined with a new U-headed dumb-bell defected ground structure (DGS) is investigated. The proposed DGS of two U-shape slots connected by a thin transverse slot is placed in the ground plane of a microstrip line. A finite cutoff frequency and attenuation pole is observed and thus, the equivalent circuit of the DGS unit can be represented by a paral...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولDesign of a 6db Directional Coupler Using Defected Ground Structure
This paper presents the design of 6dB directional coupler in C-band. A defected ground structure is used underneath the coupled region in order to relax the requirement for a narrow slot between the coupled lines. The simulated results show that the designed coupler exhibits a coupling of 6±0.1dB across the band 4.0 GHz to 4.5 GHz, when the spacing between the coupled lines is larger than 0.1 m...
متن کاملUltra-Wideband Bandpass Filter Using Hybrid Microstrip-Defected-Ground Structure
A novel ultra-wideband (UWB) bandpass filter (BPF) with a fractional bandwidth (FBW) of about % 110 is presented using the hybrid microstrip-defected-ground structure (DGS). The proposed filter was designed using a combination of hybrid microstrip-defected-ground structure lowpass filter (LPF) with typical quarter-wavelength short-circuited stubs highpass filter (HPF), followed by an optimizati...
متن کاملAn Overview on Defected Ground Structure
This paper focuses on a tutorial overview of defected ground structure (DGS). The basic conceptions and transmission characteristics of DGS are introduced and the equivalent circuit models of varieties of DGS units are also presented. Finally, the main applications of DGS in microwave technology field are summarized and the evolution trend of DGS is given.
