Problems solved by technology

However, these structures cannot achieve complete light transmission, so the efficiency of solar panels will be affected
[0005] Because the existing integration methods of antennas and solar cells cannot guarantee the maximum efficiency of antennas and solar cells at the same time

Embodiment

[0033] In this embodiment, the designed omnidirectional circularly polarized solar radiation metasurface antenna adopts the 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 located above the first dielectric layer 3 and the radiation metasurface 1 located 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 uses an Arlon AD350A plate with a dielectric constant of 3.5 and a thickness of H1, and the second dielectric layer 5 uses a Neltec NY9260 (IM) plate with a dielectric constant of 2.6 and a thickness of H2. In order to achieve a low profile, among the two dielectric layers, the second dielectric layer 5 is thinner, but to have better radiation performance, the first dielectric layer 3 needs a cer...

Abstract

The invention discloses an omnidirectional circularly polarized metasurface solar antenna, which includes a radiation metasurface of an integrated solar sky pool, a first dielectric layer, a metal floor, a second dielectric layer and a microstrip feed network from top to bottom; wherein the radiation The metasurface is a uniform array composed of multiple rectangular rings, and the solar cells are placed inside each rectangular ring; there are 4 cross-slits distributed in rotational symmetry on the metal floor, which are used to realize uniform and equal-amplitude feeding to the radiating metasurface , the feed network on the lower surface of the second dielectric layer feeds each cross slot through microstrip slot coupling feeding, and excites an orthogonal mode on the radiation metasurface to realize omnidirectional circularly polarized radiation. The radiation metasurface integrated with solar cells in the present invention basically does not interfere with each other between the performance of the solar cell and the performance of the antenna, that is, the surface area of ​​the antenna is fully utilized, and at the same time, the solar cell panel can be completely exposed to light.

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 energy metasurface antenna. Background technique [0002] With environmental pollution and green energy getting more and more attention, solar energy is favored by the market as a clean energy. When solar cells are used in the field of wireless communication, if the solar energy system and the antenna system are designed independently, the two will compete with each other for limited space resources. Therefore, the integration of antennas and solar cells has become a new technology trend. At present, integrated solar cells and antennas mainly face the following two problems: [0003] (1) When placing the solar panel directly on the antenna, such as a solar cell and slot antenna integrated device proposed in the patent application with the application number of 2016...
