Načrtovanje in izdelava radioamaterskih anten

Soko, Brin (author), Burnik, Urban (mentor)

V tej diplomski nalogi sem raziskal zasnovo, izdelavo in testiranje dveh vrst anten, Yagi-Uda in J-polne antene, ki sta priljubljeni v radioamaterskih krogih, zlasti na 2-metrskem (144-146 MHz) in 70-centimetrskem (432-440 MHz) pasu. Yagi-Uda antena, znana po svoji usmerjenosti in visokem dobitku, je bila prilagojena za usmerjeno komunikacijo na daljših razdaljah, kar je ključnega pomena za vzpostavljanje daljših zvez in izboljšanje komunikacijske učinkovitosti. J-polna antena pa je priljubljena zaradi enostavne konstrukcije, vsesmerne pokritosti in enostavnega prilagajanja impedanci. Predstavlja odlično rešitev za bazne postaje in lokalne komunikacije na terenu. V nalogi sem podrobno opisal postopek izbire, načrtovanja in optimizacije obeh anten. Zaključki naloge kažejo, da sta obe anteni primerni za specifične potrebe radioamaterjev in ponujata praktične rešitve za izboljšanje komunikacij na priljubljenih radioamaterskih pasovih. Delo tako prispeva k boljšemu razumevanju njunih lastnosti in praktični uporabi, hkrati pa odpira možnosti za nadaljnje raziskave in optimizacije.

Abstract

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.
