Abstract
Ovim radom opisuje se mjerenje djelotvornosti oklapanjem, u prvom poglavlju opisana je teorija oklapanja i fizikalni utjecaj kod propagacije elektromagnetskih valova. Kućišta koja se koriste za mjerenje djelotvornosti oklapanja napravljena su od bakra, a dimenzije su zadane u radu. Mjerenja se obavljaju pomoću signalnog generatora spojenog na odašiljačku antenu, a rezultati se uzimaju prema vrijednostima na spektralnom analizatoru koji je spojen na prijemnu monopol antenu. Mjerenja se vrše kada je antena oklopnjena kućištem, i kada se nalazi u slobodnom prostoru. Djelotvornost oklapanja se izražava kao razlika amplitude zračenja kada je antena oklopnjena i kada je u slobodnom prostoru. Oklapanjem se frekvencijski selektivno smanjuje amplituda unutar kućišta.
Abstract (english)
This paper describes the measurement of the effectiveness of shielding, the first chapter describes the theory shielding and physical effects due to propagation of electromagnetic waves. Enclosures that are used for measuring the effectiveness of shielding are made of copper, and the dimensions are given in third chapter. The measurements were made using a signal generator connected to the transmitter antenna, and the results are taken by the values of the spectral analyzer coupled to receive monopol antenna. Measurements are taken when the antenna is placed inside shielded enclosure, and when it is in free space. The effectiveness of shielding is presented as the difference between the amplitude of the radiation when the antenna is placed inside shielded enclosure and when it's placed in free space. Shielding frequency selective reduces amplitude of radiation inside enclosed space.
