A Manual Reconfigurable Multiband Cavity Backed Helical Antenna
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 16 The paper presents a miniaturized design of helical antenna loaded inside an impedance matching L-wall shaped cavity to achieve multi-frequency bands in the range of 5-15 GHz. A detail analysis of helix orientation inside the designed cavity is carried out. The cavity and helix arrangement is made reconfigurable by placing the helix and RF feed in such a way that it can thus be rotated m...

Design of Robust Sensor Nodes to Monitor Carbon Monoxide and Natural Gas Levels
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 17 In the present scenario, effective real time pollution monitoring equipments require large number of nodes (preferably >50) which are capable of interaction and hence provide reliable information. Increasing the number of sensors increases the possibility of determining the exact amount of gas levels in the surrounding environment. Hence the sensor nodes and the wireless network should t...

Design, Simulation & Performance Evaluation of OFDM System to Reduce PAPR UsingSLM & LCM with FPGA
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 15 High peak-to-average power ratio (PAPR) of the transmitted signal is a major drawback of orthogonal frequency division multiplexing (OFDM). Selected mapping (SLM) technique is one of the promising PAPR reduction techniques for OFDM. In the SLM technique, statistically independent data blocks are generated from an OFDM data block using a set of phase sequences and one with the lowest PAPR...
