Embodiment Construction
[0049] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0050] Such as figure 1 As shown, the Huygens surface 1 includes a dielectric substrate 11 and several Huygens unit structures 12 of different sizes arranged on the dielectric substrate according to the phase distribution; the Huygens unit structures are arranged regularly according to the predetermined phase, and have anisotropy ; In addition, by adjusting the geometric structure of the Huygens unit structure, the characteristics of the radiation field at the exit surface of the Huygens surface can be accurately controlled.
[0051] In engineering, in order to realize this Huygens surface, it is necessary to design a specific artificial Huygens unit structure. Such as Figure 2a ~ Figure 2d As shown, a Huygens unit structure disclosed in the present invention is given. The structure contains three metal layers and two dielectric layers, wh...

The invention discloses a Huygens surface and a control method of a new horn antenna based on the Huygens surface. The antenna puts an anisotropic Huygens artificial surface on a traditional linearly polarized horn antenna port surface; the Huygens surface is composed of a large number of anisotropic Huygens units; by designing the structure size of the units, the phase of each component of a horn antenna port surface field is changed, and finally radiation beams of the horn antenna are deflected and emitted along the designed direction; and at the same time, the polarization form of a main beam is also changed according to the design method. On the other hand, by rotating the horn antenna or the Huygens surface, the direction and polarization forms of the radiation beams are changed accordingly, and mechanical beam scanning and polarization reconstruction are realized. The new horn antenna provided by the invention can be directly used in radar detection, base station communication and satellite communication systems.
Description
technical field [0001] The invention relates to an artificial surface electromagnetic medium and a wireless communication electronic device, in particular to a Huygens surface and a control method for a novel horn antenna based on the Huygens surface. Background technique [0002] In 2013, Professor A.Grbic of the University of Michigan proposed the artificial Huygens surface in the Physical Review Letters (Phys.Rev.Lett.), and in the following years, this artificial surface has received widespread attention. [0003] At present, the use of Huygens surface has the following aspects: the use of Huygens surface realizes the control of the polarization mode of the transmitted wave, but the phase is not regulated; the use of Huygens surface is used to control the transmission phase, However, the polarization mode is not regulated; in addition, although someone has realized the simultaneous regulation of the phase and polarization mode, the design method is based on Floquet's the...
