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.

The invention discloses an edge loading structure for improving the truncation effect of a strongly coupled phased array, belonging to the technical field of antenna engineering. The edge loading structure is composed of a dielectric substrate, a semi-butterfly metal patch, and a T-shaped metal patch with a loading resistor. The semi-butterfly metal patch connected to the array edge unit guides electromagnetic waves to radiate in the form of traveling waves in the high-frequency band of the working frequency band, and together with the dipole arm and the ground plane of the array edge unit forms a single dipole antenna in the low-frequency band; the T-shaped metal patch with a loading resistor provides a grounding loop for the semi-butterfly metal patch to absorb the excess energy that has not been radiated. The invention has the advantages of simple structure, easy processing, and light weight. In the embodiment, a 32-element strongly coupled two-column linear array is designed. By comparing the active voltage standing wave ratios of the array elements during side radiation and E-plane 60° scanning before and after loading the structure described in the invention, it can be known that the proposed structure has a significant improvement effect on the truncation effect of the strongly coupled phased array.
