Design, Development and Evaluation of Directional Yagi-Uda Antenna Transmitter for an Amateur FM Radio Station at Cavite State University – Main Campus

This study describes the design, development and evaluation of a directional Yagi-Uda antenna transmitter for an amateur FM radio station at the main campus of Cavite State University. The antenna was made of an aluminum rail with a 9.525 mm diameter that includes two directors, a reflector, and a driving element. The Directional Yagi-Uda Antenna Design is the focus of the research goals for the Amateur Radio Station at Cavite State University's Main Campus, which include increasing signal strength, maximizing antenna gain, and reducing interference from unwanted signals and noise sources. These goals are intended to increase signal transmission range by at least 30%. The antenna has an operational frequency range of 88.7 MHz. A measured gain of 7.88 dBi was obtained after simulation using the YagiMAX ver. 3.11 program to assess the design attributes. Following testing at the Department of Computer and Electronics Engineering building, the prototype antenna successfully transmitted signals from the rooftop. Audible sound reception was accomplished throughout the university, with open sections experiencing particularly good reception. This study showcases the effective use of the directional Yagi-Uda transmission antenna and its enhanced signal reception capabilities for the amateur FM radio station at Cavite State University's Main Campus.
