Titel:
Imaging RFID System at 24 GHz for Object Localization 
Abstract:
A new RFID system for the ISM band at 24 GHz employing quasi-optical beam forming is presented. Active integrated antennas are used as transmitters resulting in exceptionally small size of the ID-tags. Identification codes are transmitted via a spread-spectrum modulated subcarrier that allows for very simple free running microwave oscillators as well as simple but highly selective receiver concepts. A dielectric lens and a 5 times; 5 rectenna array comprise an imaging receiver that not only iden...    »
