STRIP BRIDGE PASSIVE NON-LINEAR RADIO RESPONDER Russian patent published in 2018 - IPC H01Q1/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to passive markers-responders, which are secondary sources of electromagnetic radiation. Radio responder consists of a receiving and re-radiating antennas and a system of serially connected non-linear elements – two-terminal elements forming a four-terminal element. In this case, each of the non-linear elements is tuned to the frequency of the request signal, and the current flowing through it at the frequency of the request signal is enriched by the spectral components at the frequency of the response signal. Input of the first non-linear element is connected to the output of the second non-linear element and is connected to the first pole of the receiving antenna, the input of the fourth non-linear element is connected to the output of the third non-linear element and connected to the second pole of the receiving antenna, tuned to the frequency of the request signal. Input of the second non-linear element is connected to the input of the third non-linear element and is connected to the first pole of the re-radiating antenna tuned to the frequency of the response signal, the output of the fourth non-linear element is connected to the output of the first non-linear element and connected to the second pole of the re-radiating antenna, tuned to the frequency of the response signal. And one of the receiving and re-radiating antennas is a lattice of two closely located strip radiators, two antiphase points on which are selected as poles of the antenna, the second of the receiving or re-radiating antennas, or has a similar design, or is realized in the form of a single strip radiator on which the first pole is placed, and the second pole is located on the common ground plane of the strip receiving and re-radiating antenna system.

EFFECT: technical result consists in increase in the efficiency of the strip passive bridge non-linear radio responder use.
