Abstract: Disclosed is an RFID interrogator having a collision type identification function and a control method thereof. It verifies whether or not a collision occurs in a received signal by analyzing data of a signal received from an RF communication unit and performs a corresponding collision resolution operation by diagnosing a collision type in accordance with a collision generation means between the corresponding RFID interrogator and other interrogators or a tag. Since all types of collisions that occur between the RFID interrogator and the tag can be identified, a reason for occurrence of the collisions can be rapidly recognized to cope with the reason for the collisions.

Abstract: Provided are an RFID reader and a method for suppressing transmission leakage signals thereof. The RFID reader includes a first loop, a second loop, and a digital signal processor. The first loop suppresses a first transmission leakage signal of an RX signal in response to a first leakage control signal. The second loop suppresses a second transmission leakage signal of the RX signal, received through the first loop, in response to a second leakage control signal. The digital signal processor generates the first leakage control signal and the second leakage control signal. The digital signal processor generates the first leakage control signal until the level of the first transmission leakage signal becomes equal to or lower than the level of a first reference transmission leakage signal.
