- the input impedance of some RFID tags in the form of straps have an impedance that varies with signal length (e.g., an impedance of about three hundred and thirty ohms (330 ⁇ ) exists when the input signal level is below about negative five decibels (-5 db) and as the signal level exceeds about positive ten decibels (+10 db), the impedance decreases to less than fifty ohms (50 ⁇ )).
- an RFID tag 94 is connected to transmission line 28 by an impedance adjusting circuit comprising matching transmission line 92, which is selected to have a length to present a first impedance level to the transmission line 28 for a first signal power lever and present a second impedance level that is less than the first impedance level to the transmission line for a second signal power level that is less than the first signal power level.
- impedance adjusting circuit comprising matching transmission line 92, which is selected to have a length to present a first impedance level to the transmission line 28 for a first signal power lever and present a second impedance level that is less than the first impedance level to the transmission line for a second signal power level that is less than the first signal power level.
- matching transmission line 92 can have a length (e.g., about one quarter (1/4) wavelength) that inverts the impedance of the RFID tag 94 as presented at the junction with transmission line 28.
- a RFID tag coupled with matching transmission line 92 can be configured to have an impedance of about fifty ohms (50 ⁇ ) at high signal level and an impedance of about two hundred ohms (200 ⁇ ) at the about one hundred ohm (100 ⁇ ) transmission line 28 resulting in a weaker coupling of the strong signal to the RFID tag.
- the RFID tag If the same RFID tag has an impedance of about three hundred and thirty ohms (330 ⁇ ) at low signal level, with the matching transmission line 92 the RFID tag presents an impedance of about thirty and three tenths ohms (30.3 ⁇ ) at about the one hundred ohm (100 ⁇ ) transmission line 28, resulting in stronger coupling of the weak signal to the RFID tag.
- the higher impedance for a strong signal causes de-coupling action and a smaller portion of the signal is coupled to the tag, allowing a higher magnitude signal for tags further down the range in the stack.
- the lower impedance presented for weaker signals allows greater signal strength to be coupled to the tag for detection.
- the maximum signal coupling occurs if the RFID tag 94 and impedance adjusting circuit 92 present an impedance of about fifty ohms (50 ⁇ ) to the transmission line 92 for weak signals.
- a matching transmission line 92 having an impedance of about one hundred and twenty eight and five tenths ohms (128.5 ⁇ ) would cause the impedance presented to the transmission line 28 to be about fifty ohms (50 ⁇ ) for a low signal level and about three hundred and thirty ohms (330 ⁇ ) ohms for a high signal level.
