    摘要: A microstrip patch array antenna suppressing side lobes. The microstrip patch array antenna have a plurality of antenna array elements on two-dimensional planar having A axis and B axis for suppressing side lobes, wherein the antenna array elements are linearly arranged in a direction of the A axis by spacing a first predetermined distance between the antenna array elements, the arranged array elements are arranged in a direction of the B axis by spacing a second predetermined distance between the antenna array elements and a predetermined portion of the microstrip patch array antenna having the arranged array elements are horizontally shifted to a predetermined distance. The present invention can reduce leakage of signal or prevent to receive undesired signal and to transmit signals to undesired direction by using the above mentioned array pattern instead of reducing a distance of spacing between antenna elements.

    摘要: A battery-powered RFID tag capable of reducing power consumption and a method of waking up the RFID tag are provided. The battery-powered RFID tag has an activated mode where a general command is detected by decoding a signal received from an RFID tag reader and the general command is executed and a standby mode where the general command is not detected. If a voltage of a continuous wave detected from the signal is equal to or higher than a predetermined voltage or if a wake-up command is detected from the signal, the state of the RFID tag is changed from the standby mode to the activated mode. In addition, the RFID tag is driven by a higher one between the voltage of the continuous wave and a voltage of a built-in battery.
