  • Patent number: 12352805
    Abstract: A system and a method for testing a wireless tag that has an antenna for wireless communication and employs a low energy wireless communication protocol. The system includes a near field antenna; and a fixture for positioning the wireless tag to be tested so that the at least one antenna for wireless communication of the at least one wireless tag to be tested is within a near field of the near field antenna of the system; wherein when the wireless tag is positioned by the fixture, it is within an at least a partly open chamber. The method comprises supplying, via the near field antenna of the system, a test signal for receipt by the antenna of the wireless tag; and comparing a received signal strength of a response from the wireless tag in response to the test signal to an expected benchmark.

  • Publication number: 20240168073
    Abstract: A method and system for measuring an antenna radiation pattern of a harvester antenna printed on a substrate of an Internet of Things (IoT) tag are disclosed. The method includes sweeping a power level of a source radio frequency (RF) signal transmitted at a particular direction, wherein the source RF signal is received by the harvester antenna; measuring a transmission rate of signals transmitted by the IoT tag, wherein the transmission rate is proportional to the power level of a source RF signal received by the harvester antenna; determining if the measured transmission rate is substantially equal to a predefined threshold; registering, at each measured direction, a power level of a signal reaching a transmission rate is substantially equal to the predefined threshold; and plotting the antenna radiation pattern based on the registered power levels.
