This thesis explores the design, construction, and testing of Yagi-Uda and J-pole antennas,
which are popular among amateur radio enthusiasts, particularly in the 2-meter (144-146 MHz)
and 70-centimeter (432-440 MHz) bands. The Yagi-Uda antenna, known for its directivity and
high gain, was tailored for long-distance communications, making it ideal for establishing
longer-range connections and improving communication efficiency. The J-pole antenna, with
its simple construction, omnidirectional coverage, and easy impedance matching, serves as an
excellent solution for base stations and local communications in the field.
The thesis details the selection, design, and optimization process of both antennas.
The findings of this work indicate that both antennas are well-suited for specific amateur radio
needs and offer practical solutions to enhance communications on popular HAM radio bands.
The study contributes to a better understanding of their characteristics and practical
applications, while also paving the way for further research and optimization opportunities.
