Discontinuous loop antennas suitable for radio-frequency identification (rfid) tags, and related components, systems, and methods

摘要: Discontinuous loop antennas and related components, radio-frequency identification (RFID), tags, systems, methods are disclosed. A discontinuous antenna is an structure that includes a discontinuity portion. The can be coupled to RFID chip provide tag. portion decreases the inductance tag capacitance, thus enabling have significantly larger area while still matching impedance, resulting in dramatic increases near-field sensitivity. Increased sensitivity provides increased power harvesting efficiency during coupling. As one non-limiting example, having may achieve more from RF signal than continuous tuned same or similar resonant frequency. trimmed after fabrication allowing frequency of tuned.
