摘要： 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.

摘要： A method for testing a wireless tag by a testing unit. The method comprises: transmitting, by a first antenna, a prescribed pattern that is recognizable by a tag to put the tag into a testing mode; transmitting a trigger signal to a tag from a second antenna, the trigger signal being adapted to cause a tag to at least respond with a prescribed signal when the tag is good; waiting up to a prescribed amount of time after transmission of the trigger signal for a response to the trigger signal from a tag that is within range of the second antenna; when a valid response is received from the tag within the prescribed amount of time, designating the tag as having passed the test; and when a valid response is not received from the tag within the prescribed amount of time, designating the tag as having failed the test.
