Abstract: Predmetni izum pruža metodu određivanja smjera prolaska LF RFID taga (7) koja se bazira na konstrukciji sustava antena s prostorno segmentiranim antenama za čitanje RFID tagova (2) od jedne antene za uzbudu RFID tagova (1). Uzbudna antena (1) ima ulogu napajanja i sinkronizacije odgovora tagova, dok se na antenama za čitanje RFID tagova (2) simultano očitavaju identifikacijski brojevi. Svaka antena za čitanje RFID tagova (2) će očitati samo RFID tag (7) najbližeg objekta, pa se iz slijednog očitanja istog objekta na različitim antenama za čitanje RFID tagova (2) može odrediti smjer prolaska promatranog objekta. Ovom se metodom omogućuje gušće postavljenja RFID tagova (7) u nizu, ubrzava čitanje, povećava zalihost sustava glede grešaka u pročitanom signalu, poboljšava otpornost sustava na vanjske smetnje te omogućuje nezavisno podešavanje jačine uzbude i karakteristika antenama za čitanje RFID tagova (2).The related innovation provides for a method of determining the direction of LF RFID tag (7) passing by, based on the construction of antenna system with spatially segmented antennas for RFID tags reading (2) from one antenna for RFID tags excitation (1). The excitation antenna (1) has the task of power supply and tag feedback synchronisation, whereas on antennas for RFID tags reading (2) there are identification numbers read simultaneously. Every antenna for RFID tags reading (2) shall read only an RFID tag (7) of the nearest object, so that sequential reading of the same object on different antennas for RFID tags reading (2) enables the direction of an observed object passing by to be determined. This method enables denser setting of RFID tags (7) in a sequence, accelerates reading, increases the system redundancy considering faults in a read signal, improves the system resistance to external disturbances and enables independent adjustment of excitation intensity and characteristics of antennas for RFID tags reading (2).
