  Battery-Less Cost Effective Photo-Voltaic (PV) Smart Grid Scheme of Leading University, Bangladesh

  By Md. Niaz Morshedul Haque, Md. Ashraful Islam, Md. Sayem Miah, Md. Moontasir Rashid, Mr. Sumit Ray

  Abstract: This research paper deals with the design and simulation of a cost effective, facile and robust smart photovoltaic system for Leading University Campus, Sylhet, Bangladesh. All electrical loads have been calculated from electrical layout design using AutoCAD. Selected essential loads have also been calculated which is required for redundancy of whole electrical system. Different parameters like power consumption demands, size of the PV modules, inverter sizing, battery sizing, solar charge …

  Design and Performance Analysis of a Log Periodic Dipole Antenna with a Frequency Range of 1350 to 2690 MHz

  By Md. Ashraful Islam, Sunny Md. Shahriar Istiak, Iftekhar Rahman, Syed Aftab Uddin Tonmoy, Shaikh Muhammad Rizwan Ali

  Abstract: The introduction of broadband systems to communication and non-communication technologies has demanded the design of broadband antennas. RF antennas have relatively small bandwidth and poor directivity while the log periodic dipole antenna (LPDA) provides better directivity and gain with wide bandwidth. For a communication link and data transmission at higher rates, wider bandwidth is required with high gain and directivity. This necessitates designing a wideband antenna. In this paper, a …
