SMART GROUND STATION ANTENNA FOR EXCELLENT QUALITY OF RECEIVED DATA SIGNAL

This report constitutes of, as the title for this project, Smart Ground Station Antenna for Excellent Quality of Received Data Signal. The objective of this project is to build an intelligent antenna in order to receive with less noise signal transmitted by nano-satellite. It will be a challenging project since the distance of satellite from antenna is quite far with a lot of noise can affect the transmission process. The antenna is a 6 elements Yagi-Uda type with frequency of 434MHz. A Yagi-Uda Antenna, commonly known simply as a Yagi antenna or Yagi, is a directional antenna system consisting of an array of a dipole and additional closely coupled parasitic elements (usually a reflector and one or more directors). The dipole in the array is driven, and another element operates as a reflector. Other parasitic elements shorter than the dipole added in front of the dipole and are referred to as directors. The antenna was design using software called QY4. The antenna consists of 4 director elements, 1 driven element and 1 reflector elements. Directional antennas, such as the Yagi-Uda, are also commonly referred to as beam antennas or high-gain antennas. Yagi antenna is chosen because of good range, highly directional and easier to aim than a parabolic dish.
