Abstract
Ovaj rad opisuje postupke izrade i dizajna antene, simulaciju i mjerenje parametara lijevak antene. Komponente antene (pregrada, konus, vanjski konus, konektor) izrađene su i postavljene unutar cilindričnog valovoda. Mjerene vrijednosti parametara antene su prihvatljive, čak su neke vrijednosti blizu parametrima idealne antene. Spajanjem komercijalne antene i izrađene antene bez lijevka mjerila se polarizacija. Cirkularna polarizacija je bila na višim frekvencijama, a na nižim frekvencijama eliptična. Polarizacija izrađene antene s lijevkom na VNA uređaju prikazuje da antena ima pojačanje od 3dBi. Zbog ovakvih rezultata pokazano je kako izrađena antena radi sasvim dobro. Svrha rada je bila napraviti niskobudžetnu antenu u frekvencijskom pojasu od 3.3 GHz do 4.2 GHz s primjenom širokog pojasa, dobre usmjerenosti i cirkularne polarizacije. U ovom radu je pokazano da se mogu izmjeriti željeni parametri na prototipu i s tim informacijama bi se uvidjelo kako funkcionira realno izrađena antena.
Abstract (english)
This paper describes the antenna fabrication and design procedures, simulation and measurement of antenna funnel parameters. Antenna components (baffle, cone, outer cone, connector) are made and placed inside the cylindrical waveguide. The measured values of the antenna parameters are acceptable, even some values are close to the parameters of the ideal antenna. Polarization was measured by connecting a commercial antenna and a manufactured funnel-free antenna. Circular polarization was at higher frequencies and elliptical at lower frequencies. The polarization of the fabricated antenna with the funnel on the VNA device shows that the antenna has a gain of 3dBi. Due to these results, it has been shown that the made antenna works quite well. The purpose of the work was to make a low-budget antenna in the frequency band from 3.3 GHz to 4.2 GHz using wide band, good directivity and circular polarization. In this paper, it is shown that the desired parameters can be measured on a prototype and with this information it would be seen how a realistically made antenna works.
