摘要： The antenna of an RFID tag is automatically tuned by controlling both the real and imaginary components impedance “seen” by the antenna. The real component (resistive) is controlled by controlling a tap of a charge pump circuit of the tag. The imaginary (reactive) component is controlled by connecting one or more reactive elements of an antenna tuning circuit to the antenna. The real component is controlled by a first digital control loop that automatically activates successive taps on a charge pump of the RFID tag which effectively controls the resistance seen by the antenna. A second digital control loop controls the connection of the various reactive components.

摘要： A radio frequency identification (RFID) architecture is described. RFID tags are interrogated by a reader, which may be located in a network of readers. The reader transmits symbols to the tags. Tags respond to the interrogations with symbols that each represent one or more bits of data. An RFID tag includes an antenna pad, a receiver, a state machine, and a modulator. The receiver is coupled to the antenna pad. The receiver receives a symbol from the antenna pad and outputs a received signal. The state machine is configured to determine a response symbol from the received signal and an operating state of the tag. The modulator is coupled to the antenna pad. The modulator is configured to backscatter modulate the received symbol with the response symbol. The modulator is configured to output the backscatter modulated symbol to the antenna pad.

摘要： A method, system, and apparatus for remotely calibrating data symbols received by a radio frequency identification (RFID) tag population are described. Tags are interrogated by a reader, which may be located in a network of readers. The reader transmits data symbols to the tags. Tags respond to the interrogations with symbols that each represent one or more bits of data. To calibrate the tags, the reader transmits a plurality of pulses of different lengths to the tag population. The tags receive the plurality of pulses. A characteristic of each pulse, such as a pulse length, is stored by the tags. The stored pulse lengths are used to define different data symbols that are subsequently received by the tags from the reader.

摘要： Methods, systems, and apparatuses for RFID devices, such as tag test methods, are described. A tag of a strip of tags is positioned adjacent to an opening in an electrically conductive sheet, the tag having first and second orthogonally polarized antennas. A first RF test signal is transmitted through the opening to test the first antenna of the tag. The tag is positioned such that the first RF test signal has a polarization substantially the same as the first antenna and substantially orthogonal to a polarization of the second antenna. A second RF test signal is transmitted through the opening to test the second antenna of the tag. The tag is positioned such that the second RF test signal has a polarization substantially the same as the second antenna and substantially orthogonal to the polarization of the first antenna. If proper responses to both of the first and second RF test signals are received, the tag has passed the test. This test may be repeated for further tags in the strip of tags as desired.

摘要： Systems and methods for reducing interference by warbling a reader transmitted signal are described. To reduce interference in a densely packed multiple reader environment, a reader modulates or warbles the frequency or phase of the transmitted signal during a reception portion of a symbol exchange period. The transmitted signal is modulated within the bandwidth of an operating channel. The bandwidth of the operating channel is much narrower than the system bandwidth. In frequency warbling, the carrier frequency is shifted one or more times during the reception portion of the symbol exchange period. If phase warbling, the transmitted signal is spread within bandwidth of the operating channel during the reception portion of the symbol exchange period.
摘要翻译：描述了通过扭转读取器发送信号来减少干扰的系统和方法。为了减少在密集堆叠的多个读取器环境中的干扰，读取器在符号交换周期的接收部分期间调制或振荡发送信号的频率或相位。所发送的信号在操作信道的带宽内被调制。操作通道的带宽比系统带宽窄得多。在频率波动中，在符号交换周期的接收部分期间载波频率偏移一次或多次。如果相位波动，则在符号交换周期的接收部分期间，所发送的信号在工作信道的带宽内扩展。
