A Close-Packed Tri-Band Multi- Input Multi- Output Antenna System With DGS
Abstract: ABSTRACTIn this manuscript, A Close-packed tri-band multi input multi output antenna system with defective Ground structure for Electronic countermeasure application is proposed. Two monopoles are placed on the one end of the PCB and spaced 10mm apart. Near field of two identical monopoles creates mutual coupling that is reduced by placing metal strip (2x19) mm2 on the ground plane. The Projected Wang-formed DGS (Defective Ground Structure) of size (20x16) mm2 …

Dual Band Integrated Elliptical Slot Microstrip Patch Antenna for RF Energy Harvesting
Abstract: ABSTRACTIn this paper, a dual band microstrip patch antenna is designed for Radio Frequency Energy Harvesting (RFEH) applications. The proposed antenna covers signals from 2300 MHz to 2400 MHz and 2450 MHz to 2550 MHz. The proposed dual band patch antenna is loaded on FR-4 lossy substrate with thickness of 1.6 mm. The elliptical circle and stubs are integrated on the radiating patch which is used for increasing the resonating …

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 …

Design and Analysis of Microstrip Filtenna for 2.4 GHz Applications and Measurement of SAR over Human Head Model
Abstract: ABSTRACTMultifunctional ability of modern devices leads to wideband frequency characteristics. A microstrip antenna is a considerable narrowband antenna and a method to increase its bandwidth as well as adding filtering property is studied. In this study models are developed for 2.4 GHz band applications using filtering antenna concept that increases the bandwidth of the antenna and allows it to work as a filter to improve its frequency selectivity. In the …
