Abstract

U ovom radu opisana su svojstva valovoda, antena i valovodnih antena. Definirana su željena svojstva nove prorez antene, a korištenjem CST Studio Suita (program za modeliranje i rješavanje elektromagnetskih problema) provjeren je i prilagođen postojeći dizajn kružno polarizirane valovodne antene dr.sc. Jira Hirokawe koji je potom i izrađen. Uspoređeni su simulirani i izmjereni parametri antene: dobitka (G), aksijalnog odnosa (AR), refleksije (S11), polarizacije (RKP i LKP) za različite... More vrijednosti kuta theta θ. Simulacijom je također određen dijagram zračenja Less

Abstract (english)

In this paper, the properties of waveguides, antennas, and waveguide antennas are described. The desired characteristics of a new slot antenna are defined, and the existing design of a circularly polarized waveguide antenna by Dr. Jiro Hirokawa was verified and adjusted using CST Studio Suite (a software for modeling and solving electromagnetic problems), and was subsequently fabricated. The simulated and measured parameters of the antenna were compared: gain (G), axial ratio (AR),... More reflection (S11), polarization (RHCP and LHCP) for different values of the angle theta (θ). The radiation pattern was also determined through simulation. Less
