Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Contrast Fig. 3, one group of (4) hemisphere face di-lens 5 is row and is installed on the horizonal base plate face 7, forms hemisphere face di-lens array, and each lens 5 pairing point source 2 is positioned at sphere one side of these lens, and is connected to form a point source array 10 by linking arm 8.Linking arm 8 is hinged by support arm 9 and base plate face 7, thereby point source array 10 is rotated around the formed pivot center 11 of two pin joints, and the wave beam of hemisphere face lens arra generation also can be along 11 rotations like this.The centre of sphere 6 of each lens 5 is positioned on the pivot center 11.
Contrast Fig. 4, each hemisphere face di-lens 5 is made up of one group of hemisphere face dielectric layer 12 with the centre of sphere, and each dielectric layer has different separately dielectric constants, but dielectric property is along centre of sphere symmetry.To vigorous (Luneberg) lens of a typical spinulose tree fern, its relative dielectric constant e
rBe the function of the radial distance r from the centre of sphere to the ball surface, e
r=2-(2r/D)
2, D is the diameter of hemisphere face lens.The dielectric layer of stepping can be approximately a dielectric constant continually varying medium, thereby has simplified the making of antenna.Need to prove that the different medium numbers of plies, different dielectric materials, or even artificial medium can be used for being similar to vigorous (Luneberg) lens of replacement spinulose tree fern.Simultaneously, also can be similar to other lens with said method.Promptly, also can realize the approximate of other lenses, though the relative dielectric constant expression formula of other lenses is different from luneberg lens by selecting for use the suitable dielectric material and the medium number of plies both can realize the approximate mode of difference of luneberg lens.
During work, each hemisphere face lens 5 is point source 2 (it can be loudspeaker, dipole, paster, little band etc.) irradiation among Fig. 3 by a radiation source.The signal that comes out from each lens can make up according to different purposes (such as receiving, launch, following the tracks of), produces various directional diagrams, such as homophase addition, anti-phase difference or the like.Point source 2 is installed in from very near position, hemisphere face di-lens surface, and purpose is in order to obtain to focus on the wave beam of infinite distant place.
If point source array 10 independently is made up of the point source array of different polarization by two, such as a point source array along pivot center 11 linear polarizations, the linear polarization and another point source array and pivot center 11 are orthogonal.Two of point source array 10 arrays can independently obtain different far field polarization so, such as obtaining right-handed circular polarization and left-hand circular polarization radiation simultaneously.
Horizonal base plate face 7 can rotate around it center line 13 and rotate, and therefore the wave beam that is generated by lens can carry out 360 ° of scannings.The point source array that is connected by support arm 9 rotation axis 11 that can rotate is carried out 90 ° rotation, promptly from horizontal level to the lens tip position.But point source array 10 is all the time in a side of lens arra, and the collimated beam of sound that is generated by lens is always at the opposite side of lens arra.
Need to prove, the hemisphere face lens arra both can generate linear or fan-shaped beam, also can generate the wave beam of other shapes, and this depends on the relative size of hemisphere face lens, the quantity of lens and point source, the mode that distance between the lens and lens are illuminated by point source.The arrangement mode of hemisphere face set of lenses both can be that the foregoing description is the linear of row, also can be the rectangle of multiple row, can also be arranged in other geometry.
