Embodiment Construction

[0066] The present invention will be further described below in conjunction with embodiment and accompanying drawing. Among them, the terms "first", "second", etc. are limited to the purpose of description, and cannot be understood as limitations on quantity, etc.; and the term "connection", interpreted in a broad sense, can be either a mechanical connection or an electrical connection. connection, or signal connection, etc.

[0067] For example, 1 is a schematic diagram of the application scene of the transparent antenna in the embodiment of the present invention. The transparent antenna is mainly installed on the low-orbit satellite for inter-satellite communication with the high-orbit satellite. Of course, it can also be applied to other spacecraft. for communication.

[0068] Such as figure 2 As shown, in the embodiment of the present invention, the transparent antenna includes a solar panel 100, an antenna array and an antenna circuit. Wherein, the antenna array inclu...

Abstract

The invention discloses a satellite-borne multi-beam switching transparent antenna, and belongs to the technical field of antennas. The antenna comprises a solar panel, an antenna array plane and an antenna circuit; the antenna array surface is arranged above the light-facing surface of the solar panel, and a gap is formed between the antenna array surface and the solar panel; the antenna array surface comprises a receiving antenna array surface and a transmitting antenna array surface; each of the receiving antenna array surface and the transmitting antenna array surface comprises a transparent substrate, a micro-strip antenna array and a feed network which are arranged on a light-facing surface of the transparent substrate, and a grounding surface arranged on a backlight surface of the transparent substrate, the micro-strip antenna array is connected with the feed network, and the micro-strip antenna array, the feed network and the grounding surface are all of a transparent structure; and the antenna circuit is arranged on the backlight face of the solar panel and comprises a receiving antenna circuit and a transmitting antenna circuit. According to the invention, the array surface of the antenna is transparent and is integrated with the solar panel, so that the radiation capacity of the antenna is improved, and the communication load capacity of a satellite is further improved.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a space-borne multi-beam switching transparent antenna. Background technique [0002] LEO satellites have the advantages of short transmission delay and small path loss, and have important application value in mobile satellite communication and space-based Internet of Things. The establishment of inter-satellite transmission links between low-orbit satellites and geostationary orbit satellites can improve the service coverage of low-orbit satellites on the earth. With the increase of ground service requirements, the demand for low-orbit satellite loads has transitioned from the single working mode in the past to the multi-task mode. This change in business requirements requires the load of low-orbit satellites to increase the number of satellite-borne antennas and increase the antenna gain. However, the space of the small satellite platform is limited. Using the tr...
