Power Amplification based on Bulk-Drive
Abstract: ABSTRACTThis paper presents a fully integrated, low transmit-power and high-efficiency power amplifier (PA) for low-power transmitters such as wireless sensor networks (WSN). Power Amplification is a major problem in power system network all over the world, which is illegal and should be strictly prohibited, it is highly impossible due to the linear relation between Voltage and Current. Power amplification can be defined as the amplification of the electrical power without …

Gain Enhancement with Microstrip Patch Antenna Array and Slot
Abstract: ABSTRACTIn this study, a microstrip fed patch antenna array for application in the ISM band was implemented using the HFSS software. A slot antenna array was designed with the purpose of gain enhancement as well as reduction of return loss. There is some fluctuations from the desired design frequency due to some designing error and some imperfection in the impedance matching at the feeding point which can be further be …

Arduino Based Traffic Light Control System Using NRF Module
Abstract: ABSTRACTTraffic congestion is a major problem for any contemporary major city. Transportation systems are heavily burdened due to traffic congestion. A major impact of slow moving traffic is the danger posed to critical vehicles like an ambulance as it can cause loss of human capital to any country. A possible solution is to automate the traffic signal controlling mechanism by allowing real time monitoring. Such an approach is expected to …

Gain Enhancement of a Filtenna Using Defected Ground Structures Technique
Abstract: This paper presents a compact filtenna with enhanced gain by improving the structural shape of filtenna using defected ground structure(DGS) technique. A filtenna is an integration of a filter and an antenna into a one device. This combination leads to the reduction in the system size, weight cost and complexities. The proposed filtenna consists of a hairpin bandpass filter and a hexagonal-shaped microstrip patch antenna. The filtenna without DGS has …

Synthesis and characterization of bi metallic Nanoparticles by 2-thiotic acid for selective growth of SWCNT
Abstract: Nanoparticles (NPs) are tiny materials having size ranges from 1 to 100 nm. They can be classified into different classes based on their properties, shapes or sizes. There are different types of NPs like men made NPs and Natural NPs but we are discussing about monometallic NPs and Bimetallic NPs. We deal with bimetallic NPs. NPs possess unique physical and chemical properties due to their high surface area and nanoscale …
