3.7. LFantennas
LF antenna generates RFID zones by transmitting in a frequency of 125 KHz and sending data. By
generatingtheRFzones,atagthatis intherange ofthedetection area oftheantenna,is excitedand
receivesdatatransferredfromtheunitthroughtheRFIDfield
andeventuallytothetag.Oncethetagis
excited,thetagstartstotransmitonUHFband,directlytothemainun it.Afterthetaghastransmitted
totheunitandreceivingprocesshasbeenmade,theunitsendsaconfirmationsignalonUHFbandto
thetagand
confirmingthatthedatahasarrived.
Theantennainstallationshouldbeinthecorrectangle(describedinthenextsection),whichaffectsthe
receptionareaofthetags.
Bylocatingtheantennaincorrectposition,thesystemenablesawidedetectionrange.
