A Novel Passive Phase Modulator based on LH Delay Lines for Chipless Microwave RFID Applications

Mandel, Christian and Schüßler, Martin and Maasch, Matthias and Jakoby, Rolf (2009):
A Novel Passive Phase Modulator based on LH Delay Lines for Chipless Microwave RFID Applications.
In: IEEE MTT-S International Microwave Workshop on Wireless Sensing, Local Positioning, and RFID, [Conference or Workshop Item]

Abstract

This paper discusses novel techniques to overcome problems arising when porting the surface acoustic wave approach of building passive radio-frequency identification and measurement systems to the electromagnetic domain without the need of mechanical (acoustical) delay lines. These techniques include the utilization of left-handed artificial delay lines and the increase of information density by using a higher order modulation scheme. The benefit from the porting is a broader field of applications, e. g. RFID tags working at very high temperatures or in other harsh environments become possible.
