Construction of smart city has become a historical trend in the world. The management of underground pipes and the intelligent concrete are the main part of building smart city in China. Compared with the available electronic marker system, SAW-RFID system has shown excellent properties: truly passive, strong penetrating capability, long service-life, sensing and ID integration, and etc. Thus, SAW-RFID...
Some methods to enhance penetration depth further are proposed and demonstrated. A second harmonics SPUDT, new criterion of matching and high reflectivity reflector are utilized to reduce the losses of SAW tag. The enhancement of reading system including high signal processing gain and compensate the center frequency mismatch between reader and SAW tag are achieved. Furthermore, the effect of decreasing...
It is increasingly urgent to improve the intelligent level of the equipment management for modern international airports. This is the first attempt of SAW RFID on aerodrome lights. SAW tag with temperature sensing function and anti-metal patch antennas are designed. The position of the tag fixed in different kinds of lights such as the runway light and the taxiway light is demonstrated. The experimental...
