Abstract: An antenna device and a wireless mobile terminal. The antenna device includes: a frame including a border and a hollow space surrounded and formed by the border; a support connected to the border and extending towards the hollow space; and an antenna assembly including a first antenna module and a second antenna module. The first antenna module is arranged on the support and includes a plurality of first antenna units distributed at intervals, and the second antenna module includes a plurality of second antenna units. The first antenna module and the support are insulated from each other, and the support includes a conductive material and is reused as at least a portion of the second antenna units.

Abstract: An omnidirectional ghost imaging system based on a mechanism of bio-inspired retina-like includes a projection system, a collimating lens, a spectroscope, a curved mirror, a bucket detector, a data acquisition card and an arithmetic system. According to the application, the logarithmic polar mapping characteristic of the bio-inspired retina-like structure is utilized to generate an annular pattern sequence of the bio-inspired retina-like, and the pattern sequence is utilized to modulate a light source. After being reflected by the target around the curved mirror, the light is projected onto the curved mirror and diffusely reflected. According to the reversible characteristics of the optical path, the light after diffuse reflection is reflected to the original light source by the half mirror and half lens, and the reflected light intensity with target information is received by the bucket detector.

According to the reversible characteristics of the optical path, the light after diffuse reflection is reflected to the original light source by the half mirror and half lens, and the reflected light intensity with target information is received by the bucket detector. The reflected light intensity measurement value with target information is correlated with the annular pattern sequence of bio-inspired retina-like used for modulating the light source.
