Integrated solar cell and slot antenna device

Abstract

The invention discloses a solar cell and slot antenna integration device, which comprises a slot antenna, a solar cell, a metal floor, a dielectric substrate and a microstrip line, and is characterized in that the metal floor is located on the dielectric substrate, the slot antenna is arranged on the metal floor, the microstrip line covers the lower part of the dielectric substrate and feeds energy for the slot antenna, the microstrip line and the slot antenna form electromagnetic coupling so as to generate electromagnetic radiation; the solar cell is located on the metal floor and does not cover the slot antenna, and the slot antenna runs through the solar cell and the metal floor; and the metal floor acts as a common horizontal plane of the slot antenna and the solar cell. The solar cell and slot antenna integration device solves a problem that the solar cell and the antenna system mutually compete for space resources at the limited surface of a micro-nano satellite, the volume of the satellite is reduced, the weight of the satellite is reduced, and the light receiving area of the solar cell is increased.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and relates to a solar cell and slot antenna integration device used on a three-dimensional micro-nano satellite. Background technique [0002] Micro-nano-satellites are currently a research hotspot in the field of aerospace science and space technology. Due to the characteristics of small size, low power consumption, short development cycle and formation networking, micro-nano-satellites can complete many complex space tasks at a relatively low cost. . However, due to volume and mass limitations, the load capacity of micro-nano satellites is limited, and their functions and on-orbit tasks are relatively single. At present, solar cells and antenna systems take up 1 / 4 to 1 / 3 of the weight of micro-nano satellites, and solar cells and antenna systems are designed independently, and the two compete with each other for the extremely limited space resources on the satellite.
