摘要

the invention relates to radio engineering and is used predominantly in the range of uhf rfid systems in order to improve the u044du0444u0444u0435u043au0442u0438u0432u043d guests of the system in the form of an increase in the range and increasing the likelihood of identifying rfid tag (transponder) with u0443u0441u043bu043eu0432 u0438u044fu0445 limited space.the essence of the method is to subdivide into a circular u043fu043eu043bu044fu0440u0438u0437u0430u0446u0438u043eu043du043du043eu043c basis according to the fields and u043au0440u043eu0441u0441u043eu0432u043eu0439, backscatter from the incidence surface ra u0434u0438u043eu0432u043eu043bu043d falling on the mark forming at least two channels for the provision of the information signal and the constant component of each channel and u043fu043eu0441u043bu0435u0434u0443u044eu0449 eat u043du0435u043au043eu0433u0435u0440u0435u043du0442u043du043eu043c folding signalsthe information code sequence and a constant component. to realize the u043du0435u043au043eu0433u0435u0440u0435u043du0442u043du043eu0435 addition signals becomes possible due to the difference of phases of signals with orthogonal u043fu043eu043bu044fu0440u0438u0437u0430u0446u0438u044fu043cu0438 consistency in each case de polarization by reflection from the surface of azerbaijan, all the angles of the radio waves, in which the real conditions of operating system ma.the technical effect is achieved through the use of the energy of radio waves produced by these u0441u0447u0438u0442u044bu0432u0430u044eu0449u0438u043c device that can increase the probability of retrieving identification tags and the range of the operation in the limited space.
