Abstract
U ovom diplomskom radu obraden je postupak automatiziranog i integriranog projektiranja i aditivne proizvodnje lijevak antene i pobudnog adaptera, ispitan na primjerima antena sa središnjim frekvencijama 2437 MHz i 5250 MHz. Četiri antene proizvedene su tehnikom 3D ispisa, te su njihove frekvencijske karakteristike i dijagrami zračenja izmjereni u laboratoriju. Za svaku ciljanu središnju frekvenciju proizvedena je jedna antena projektirana tradicionalnim metodama, te druga projektirana automatiziranim optimizacijskim algoritmom. Proizvedena antena s optimiziranim parametrima i ciljanom središnjom frekvencijom u iznosu 2437 MHz postigla je vrijednost S11 parametra u iznosu −16 dB na 2437 MHz, s lokalnim minimumom u iznosu −30.9 dB na 2351 MHz. Antena s optimiziranim parametrima, za središnju frekvenciju 5250 MHz postigla je na ciljanoj središnjoj frekvenciji vrijednost S11 parametra u iznosu −12.34 dB, s lokalnim minimumom u iznosu −30 dB na 4938 MHz. Vršni dobitak svih proizvedenih antena s optimiziranim parametrima odgovara željenoj vrijednosti od 10 dB.
Abstract (english)
An automated and streamlined design and optimization process of a horn antenna and waveguide to coaxial adapter is proposed. Antennas with central frequencies of 2437 MHz and 5250 MHz are designed with the automated design and optimization algorhythm. Total of four antennas were manufactured with a 3D printer. For each central frequency, one of the antennas is designed with traditional design tecniques, whilst the other is designed with the automated design and optimization algorhythm. Manufactured antenna designed for central frequency of 2437 MHz achieved the S11 parameter value of −16 dB at the designed central frequency, with local minima of −30.9 dB at 2351 MHz. Antenna designed for 5250 MHz central frequency achieved the S11 value of −12.34 dB at the designed central frequency, with local minima of −30 dB at 4938 MHz. Peak gain of all manufactured antennas with optimized parameters is measured at 10dB, which is in agreement to the design value.
