摘要： The present invention provides an antenna for an RFID system, including a conductor line (8), wherein the conductor line includes at least two loop parts (80, 82) and at least one connecting part (81). Successive loop parts (80,82) are connected by a connecting part (81). The connecting part is disposed in such a manner as to be separated from said loop. Although the loop circumference is in the order of a wavelength the connecting part (81) ensures the current on the loop parts (80, 82) to flow in the same diretion. Thus, the antenna can attain a sufficient size in a UHF RFID system and satisfy the reading distance requirement for a near-field UHF RFID reader. Alternative solutions for the connecting part are detour lines and phase shifting devices.

The method includes the following steps: firstly, said reader/writers read at least two from said group of tags, capture the received signal strength indication envelopes of said tags, and store the received signal strength indication envelope of one of the tags as a template; secondly, a correlation match is performed for the received signal strength indication envelope of said tags and said template to obtain the time interval between the received signal strength indication envelope of said tags and said template when the correlation value is the maximum. Using the present invention, the reader/writer can report each tag in front of the antenna, even if multiple tags exist in the complicated industrial environment, ensuring FCFR and improving the reliability of the UHF RFID system.

摘要： Das Verfahren betrifft die Übertragung von Daten eines mobilen Datenspeichers (DT) an ein Schreib-/Lesegerät (SLG), insbesondere über eine Luftschnittstelle (LS), wobei die Daten in einem programmierbaren elektronischen Speicher (MEM) mit einer festen Speichergröße (FIX) hinterlegt werden können. Erfindungsgemäß wird nur eine vorgebbare Menge von Nutzdaten (DATA) aus dem elektronischen Speicher, insbesondere zyklisch, übertragen. Damit ist der Vorteil verbunden, dass nur die benötigte, von einem Anwender programmierbare Anzahl (ANZ) von Nutzdaten übertragen wird. Damit ist vorteilhaft eine Erhöhung der Überfahrgeschwindigkeit und/oder der übertragbaren Datenmenge zwischen mobilem Datenspeicher und Schreib-/Lesegerät möglich. Das Verfahren kann vorteilhaft bei mobilen Datenspeichern und bei Identifikationssystemen (IS) mit einem Schreib-/Lesegeräten (SLG) und zumindest einem mobilen Datenspeicher eingesetzt werden.
