Planar lens antenna with self-sustaining capability

Abstract

The invention discloses a planar lens antenna with self-sustaining capability. The planar lens antenna comprises a planar lens structure and a space feed structure; the planar lens structure comprises a thin-film solar charging structure, a top-layer wave-transparent structure, a bottom-layer wave-transparent structure and a phase-shifting structure, the top-layer wave-transparent structure, the bottom-layer wave-transparent structure and the phase-shifting structure are in transition connection through coupling holes or microstrip lines, and the thin-film solar charging structure and the top-layer wave-transparent structure are integrated together; and the space feed structure is arranged below the bottom-layer wave-transparent structure and provides feed for the plane lens structure. The thin-film solar charging structure and the planar lens structure are integrated together, the production cost is low, large-scale manufacturing can be achieved through a display panel production line process, and the planar lens antenna has the advantages of being low in power consumption, low in outline, capable of being self-held, flexible in design and use, capable of conducting electronic beam scanning and the like.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a planar lens antenna with self-sustaining capability. Background technique [0002] In the fields of the Internet of Things, buoys, field environmental monitoring, etc., unattended antenna devices that can communicate with satellites are often required. For the use environment with small data volumes, such as regularly uploading the current temperature, humidity and other small data volumes of the detected objects , the usual practice is to use a wide-beam low-gain fixed-beam antenna and use a thin-film solar panel or battery to supply power; for a large amount of data usage environment, such as uploading monitoring videos, etc., usually use a mechanically rotating parabolic antenna or a horn array antenna And generators and other electrical equipment power supply. The former has a small communication bandwidth and cannot communicate with a large amount of data. Although the l...

Problems solved by technology

The former has a small communication bandwidth and cannot communicate with a large amount of data. Although the latter can transmit large data, the huge support equipment and power consumption always restrict its further development.

[0003] The existing technology has problems such as small communication capacity, high use cost, demanding use environment, high power consumption, and inability to perform electronic beam scanning. An electronic beam scanning with flexible working mode, low profile, low cost, low power consumption and easy integration Antennas become necessary
