Embodiment

[0032] In this embodiment, the designed omnidirectional circularly polarized solar radiation metasurface antenna adopts microstrip slot coupling feeding in the feeding mode, see figure 1 , the metal floor 4 is between the first dielectric layer 3 and the second dielectric layer 5, and the radiation metasurface 1 above the first dielectric layer 3 and the radiation metasurface 1 below the second dielectric layer 5 are realized through the gap of the ground plane. Coupling of energy between microstrip feed networks 6 . In this embodiment, the first dielectric layer 3 is made of Arlon AD350A board with a dielectric constant of 3.5, with a thickness of H1, and the second dielectric layer 5 is made of a Neltec NY9260 (IM) board with a dielectric constant of 2.6, with a thickness of H2. In order to achieve a low profile, among the two dielectric layers, the second dielectric layer 5 is thinner, and to have better radiation performance, the first dielectric layer 3 needs a certain th...

Abstract

The invention discloses an omni-directional circularly polarized metasurface solar antenna. The omni-directional circularly polarized metasurface solar antenna comprises a radiation metasurface integrated with a solar cell, a first dielectric layer, a metal floor, a second dielectric layer and a micro-strip feed network from top to bottom, wherein the radiation metasurface is a uniform array formed by a plurality of rectangular rings, and the solar cells are placed inside the respective rectangular rings; four cross-shaped cross gaps which are symmetrically distributed in a rotating mode are formed in the metal floor and are used for achieving uniform equal-amplitude feeding of the radiation metasurface; and a feeding network on the lower surface of the second dielectric layer is used forfeeding each cross-shaped cross gap in a microstrip gap coupling feeding mode to excite an orthogonal mode on the radiation metasurface, so that omni-directional circularly polarized radiation is realized. According to the solar antenna, the performance of the solar cell integrated with the solar cell radiation metasurface and the performance of the antenna are basically not mutually interfered, so that the surface area of the antenna is fully utilized, and meanwhile, it is ensured that the solar cell panel can be completely exposed under illumination.

Description

technical field [0001] The invention belongs to the application field of solar photovoltaic and wireless signal transmission technology, and in particular relates to an omnidirectional circularly polarized solar metasurface antenna. Background technique [0002] As environmental pollution and green energy are getting more and more attention from all sides, solar energy, as a clean energy source, has been favored by the market. When the solar cell is applied in the field of wireless communication, if the solar system and the antenna system are independently designed, the two will compete with each other for limited space resources. Therefore, integrating antennas and solar cells has become a new technical trend. At present, integrated solar cells and antennas mainly face the following two problems: [0003] (1) When placing the solar cell panel directly on the antenna, such as a solar cell and slot antenna integrated device proposed in the patent application No. 20161115486...
