The application discloses a multi-circle gradually-changing impedance edge loading tight field device, which is a novel device different from traditional sawtooth tight field and edge curl tight field. The device sprays conductive paint with gradually-changing impedance on the edge of a parabolic surface in multiple circles, and controls the impedance value of the conductive paint in the gradually-changing manner. Compared with common sawtooth edge processing and edge curl processing, the design of the multi-circle gradually-changing impedance does not need to process the edge shape into sawtooth or curve, but only needs to load impedance on the edge surface of the parabolic reflecting surface, so that the processing steps of the tight field reflecting surface are greatly simplified, the processing difficulty is reduced, and the cost is saved. The device disclosed by the application fully meets the performance indexes of the tight field, can be used as an upgrade and substitution of the existing tight field product, and is one of the development trends of future low-frequency test fields.
