SENSOR FOR IDENTIFICATION OF STRUCTURES LOCATED AT LARGE DEPTH Russian patent published in 2021 - IPC G06K19/07 H01Q1/04 

FIELD: wireless communication.

SUBSTANCE: invention relates to a transceiver for wireless communication system and contactless identification of RFID-type. The transceiver contains a set of antenna segments consisting of electrical wires forming at least first and second antenna elements (203-1, 203-2), connector (281) containing RFID chip and at least one tuning capacitance (202x), as well as communication means providing electrical connection of the specified antenna segments, in which the specified antenna segments are located next to each other at a distance less than 3 mm, which allows providing communication capacitance values that can extend the range of allowances for the RFID resonant frequency. The transceiver contains a printed circuit containing connector (281) for connecting three antenna segments (701, 702, 703). Specified connector (281) contains first (284-1), second (284-2) and third (284-3) input electrodes for connecting, respectively, the first end of first (701), second (702) and third (703) antenna segments, and fourth (285-1), fifth (285-2) and sixth (285-3) output electrodes for connecting the second end of specified first (701), second (702) and third (703) antenna segments. The specified printed circuit contains first circuit (286-3) for connecting first input electrode (284-1) to sixth output electrode (285-3) via RFID chip, second circuit (286-1) for connecting second input electrode (284-2) to fourth output electrode (285-1), and third circuit (286-2) for connecting third input electrode (284-3) to fifth output electrode (285-2) via capacitor (202x).

EFFECT: provided is a possibility of detecting and identifying a sunken structure.
