Abstract
Najveća prednost antena je ta što se komunikacija ili prijenos podataka može odvijati na velikim udaljenostima bez ikakvih vodiča, valovi koje antena odašilje se gibaju u slobodnom prostoru bez upotrebe vođenih prijenosnih medija. Koriste se u komunikaciji satelitima, prekooceanskoj komunikaciji pa sve do odašiljanja wi-fi signala u kući, te mnoge druge primjene. U ovom radu korištene su dipol antene, te su modificirane dodavanjem vodljivih traka na stražnjoj podlozi antena. U radu su izvedena mjerenja S11 parametara i Smithovog dijagrama na frekvenciji od 30 khz do 6,5 Ghz. Mjerenja su izvršena na Keysight N9914A RF analizatoru. Iz S11 parametara saznat je koeficijent refleksije, a iz Smithovog dijagrama ulazna impedancija te fazni kut. Svi dobiveni podaci su analizirani i komentirani.
Abstract (english)
The biggest advantage of antennas is that communication or data transmission can take place over long distances without any conductors, waves that antenna emits move in free space without the usage of guided transmission media. They are used in satellite communications, overseas communications, even wi-fi signaling at home, and many other applications. In this paper dipole antennas were used and modified by measuring the S11 parameters and the Smith Diagram at a frequency of 30 kHz to 6.5 Ghz. The measurements were performed on the Keysight N9914A RF Analyzer. From S11 parameters we find the reflection coefficient, and from the Smith Diagram the input impedance and the phase angle. All the data obtained was analyzed and commented.
