Parallel coupled bandpass filter is proposed and designed by placing defected ground structure (DGS) in the ground plane. The proposed open loop dumbbell shaped DGS is used to tuned the bandpass filter to 6 GHz with a dimension of 50mm × 25mm. The bandpass filter is designed by using FR-4 printed circuit board and a tuning range of 0.994 GHz is achieved. This filter gives an insertion loss of −5.784...
Many fast Block Matching Algorithm or BMA have been proposed and developed in recent years in order to reduce the computational cost while maintaining the quality of the video signal. In this paper, a new Orthogonal-Diamond Search (ODS) is proposed which employs an orthogonal-shaped search pattern in the first step and then is switched into small diamond-shaped search pattern for the next step. The...
This paper represents design of 3GHz hairpin filter with Defected Ground Structure (DGS) for Microwave Imaging application by using Advanced Design System (ADS) software and FR4 substrate. Hairpin filter is one of the most popular microwave filters because of its compactness. Thus, to enhance its performance detected ground structure is implemented to the filter. The filter is designed to operate...
This paper presents the analysis of bending optical waveguide based on effective refractive index and beta propagation constant. The various sample of core waveguide size such as 3 ×3, 7×7 and 9×9 is taken and measure with radius curvature of optical waveguide. The data collection based on Maxwell equation derivation and modeling electromagnetic field as a engine behind of graphical user interface...
This paper presents comparison on IV Characteristics analysis between Silicon and InGaAs PIN Photodiode. PIN Photodiode is a structure that is consists of positive region, intrinsic region and negative region (PIN). The thick intrinsic regions are a difference to a normal PN Photodiode. PIN Photodiodes practical as Photodetectors, Attenuators and Radio frequency (RF) switches. The simple, low cost...
The analysis of dielectric constant of pharmaceutical medicines at microwave frequency is presented in this paper. The dielectric constant also known as the permittivity was measured by using open-ended coaxial probe technique over the microwave frequency range from 400Mhz to 4GHz. The samples of two pharmaceutical medicines were prepared at different moisture content (5ml, 10ml, 15ml, 20ml, 25ml...
This paper describes the design of Low-pass filter using bowtie Defected Ground Structure (DGS). The designing of low-pass filter begins from lumped element in which the filter will be built using capacitors and inductors before converted to open and short circuited stub. The low-pass filter using bowtie Defected Ground Structure (DGS) is required to operate at 10 GHz for radar application. As a comparison,...
This paper proposed a design of SDR Silicon IMPATT diode in lateral structure and analyzes the variable junction temperature analysis in Silicon IMPATT diode. The simulation on the effect of junction temperature on electric field and carrier mobility is carried out for Si SDR IMPATT structure designed at D-band frequency. Result show that electric field increases while the carrier mobility decreases...
In PCB holes drilling process, the time taken for a task completion heavily rely on the distance travels by the drill bit of the CNC machine. In order to minimize the distance traveled by the drill bit, Firefly Algorithm can be used. The proposed model applies Firefly Algorithm to search for the optimized path in PCB holes drilling process. Each agent's position represented a possible path that can...
This paper describes the design of low noise amplifier using enhancement mode technology for WLAN front-end applications. Typical LNA designed for the IEEE802.1a standard is required to operate with low noise, high gain and exhibit low noise figure. The design uses feedback, and balanced topology to enhance the performance and to achieve the design goal. The LNA is designed operate at 2.4GHz, noise...
