Description

TECHNICAL FIELD

[0001] The application belongs to the field of electromagnetic field and microwave technology, and particularly relates to a columnar conformal reconfigurable holographic surface antenna with dynamic radiation and scattering regulation. BACKGROUND

[0002] As a two-dimensional form of artificial composite electromagnetic material, metasurface can realize complex regulation of electromagnetic wave inherent properties by introducing field discontinuity on the interface of electromagnetic wave incidence. However, the current beam regulation antenna based on metasurface is mainly composed of passive metasurface units, that is, the electromagnetic response and function of the unit are fixed, which cannot meet the dynamic regulation demand in actual application.

[0003] Reconfigurable technology provides a new working mechanism for realizing active metasurface. By loading external control circuit on active devices, electromagnetic wave propagation is regulated in real time to form a tunable metasurface. In the existing design of tunable metasurface, the adjustable devices on the metasurface are controlled, so that the radiation wave can be regulated to realize the characteristics of beam scanning, or the scattering wave beam can be regulated, but it is difficult to design independent regulation of radiation beam and scattering beam. In addition, under the development demand of environmental complexity and functional diversification, single function cannot meet the growing demand, and the realization of multi-functional electromagnetic wave regulation gradually becomes one of the research hotspots of metasurface. In addition, the current active metasurface antenna is mostly in planar structure. When the antenna is conformal to the columnar carrier platform, it is difficult to realize stable beam regulation.

[0004] The metasurface antenna based on holographic principle has the advantages of low profile, simple feed design, easy conformal and low processing cost, so that the holographic surface antenna can be applied to miniaturization, conformalization and radar detection of wireless communication application scenarios. Once the holographic pattern of the traditional holographic antenna is established, its far-field pattern is also fixed, which cannot meet the demand of wireless communication. The design of reconfigurable holographic surface antenna improves the deficiency of traditional holographic surface antenna, and realizes dynamic beam forming without complex mechanical movement device and phase shift circuit. The existing research work is roughly concentrated on realizing single-function reconfigurable holographic surface antenna on a planar platform, and only proves the feasibility of realizing dynamic beam regulation by reconfigurable holographic surface. At present, there is no method for dynamically regulating the radiation and scattering beams of conformal reconfigurable holographic surface. SUMMARY

DETAILED DESCRIPTION

[0035] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and embodiments.

Therefore, the present application provides a cylindrical conformal reconfigurable holographic surface antenna for dynamic control of radiation and scattering, which realizes dynamic scanning of beams within the range of-50°-50°, beam splitting and directional control within ±60° under the vertical incident plane wave in the scattering state, enhanced scattering directivity within ±60° under the oblique incidence, and effectively reduces the radar scattering cross section through uniform suppression of scattering. It has the characteristics of incident angle insensitivity and low radar scattering cross section, and is suitable for applications in the fields of wireless communication and radar detection in complex environments, etc.

[0037] To further illustrate the effect of the present application, specific embodiments are given.

[0038] REFERENCE Figure 1As shown, the radiation and scattering dynamically regulated cylindrical conformal reconfigurable holographic surface antenna of the application comprises a radiator 1 and a feed source 2 located at the center of the radiator 1; the radiator 1 is composed of 440 conformal reconfigurable holographic surface units 11 and has a cylindrical structure. The feed source 2 adopts a monopole antenna structure. The center of the monopole antenna cylindrical conductor coincides with the normal line of the center of the radiator 1 to generate a surface wave.

[0039] In the application, the modulation ability of the conformal reconfigurable holographic surface unit 11 to the surface wave is used, and the cylindrical structure of the radiator 1 obtained by arranging the array of the conformal reconfigurable holographic surface unit 11 modulates the surface wave into a radiation wave.
