The invention relates to the field of electromagnetic antennas, in particular to a power line carrier radiation detection antenna system. The power line carrier radiation detection antenna system comprises a shielding box, wherein a PCB circuit substrate and a magnetic bar antenna fixed on the PCB circuit substrate are arranged in the shielding box, a closed space formed by the shielding box shields interference signals from the outside, the magnetic rod antenna receives a power line carrier radiation signal of a power line, and interference radiation is amplified by the electric signal amplification assembly on the PCB circuit unit and filtered by the interference wave filtering assembly, Through adopting the power line carrier radiation detection antenna system, high signal-to-noise ratio detection can be efficiently and quickly performed on power line carrier space radiation signals; and the power line carrier radiation detection antenna system has the advantages of low loss, stronganti-interference, high gain, ultra wide band, miniaturization and modularization.
Description
technical field [0001] The invention relates to the field of electromagnetic waves and antennas, in particular to a power carrier radiation detection antenna system. Background technique [0002] Power carrier is a unique method in the power system. The realization of power carrier is the technology of high-speed transmission of analog or digital signals through the use of existing power lines. When the power carrier is connected to the terminal equipment, an electromagnetic signal will be generated and transmitted through the power line, and the electromagnetic signal will radiate to space through the power line. By detecting this radiation signal, the connection state and physical distribution of the power line can be evaluated. [0003] The electromagnetic radiation generated when the power carrier passes through the wire is relatively weak, coupled with the interference of external electromagnetic signals, the effect of directly detecting the radiation generated by the ...
