The design of a 920 MHz active oscillator antenna using low cost flexible substrate materials is presented. Flexible amorphous silicon a-Si solar cells are properly integrated in the available area of the circuit substrate preserving the conformal nature of the circuit and providing operational autonomy by harvesting solar power without affecting the radiation properties of the active antenna. Coplanar...
In this talk, inkjet-printed flexible antennas, RF electronics and sensors fabricated on paper and other polymer (e.g. LCP) substrates are introduced as a system-level solution for ultra-low-cost mass production of UHF Radio Frequency Identification (RFID) Tags and RFID-enabled Wireless Sensor Nodes (WSN's) in an approach that could be easily expanded to other microwave and wireless “cognition” applications...
