RFID Transponder

Detuning

When a transponder is placed adjacent to a metallic object then this can detune its resonance and drastically reduce the read range. Our system provides improved tolerance to environmental detuning.

Range

The use of a high efficiency antenna in the tag gives greater read range. The tag naturally tunes to the interrogation field frequency without requiring external power to run a separate tuning circuit. The low loss leads to a greater voltage step-up, with the minimum read field at a greater distance.

Cost

Relaxation of the required manufacturing tolerances are expected to lead to cost savings. Further areas for savings include the property that the resonance naturally regulates to a fixed voltage, eliminating the need for a separate regulator for high field strengths.

Multi-Band Operation

If the same tag is required to respond to multiple frequencies then this may be achieved through the design of the operating band.
