  A Survey on Fractal Antennas

  By Raja Ch., K Praveen Kumar

  Abstract: Modern communication systems demand antennas with (1) compact size, (2) low profile, and (3) multi or broadband characteristics without altering antenna properties moreover, if possible enhancement should obtain. “The Fractal Antenna” operates at all ideal characteristics. So the present paper considers different fractal geometries, and its operation as antenna

  Fuzzy Based Power Flow Control in Grid Connected Hybrid PV-PEMFC Microgrid System

  By Raja Ch., Praveenkumar K K.

  Abstract: This paper evaluates the performance of a fuzzy based power flow control of grid connected hybrid system. The hybrid system composed of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC) is considered. The photovoltaic (PV) array normally uses a maximum power point tracking (MPPT) technique to continuously deliver the highest power to the load when there are variations in irradiation and temperature occur, which make it …
