Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an antenna body device used in a stratospheric environment. Background technique [0002] The stratosphere, also known as the stratosphere, is the hotter upper layer and cooler lower layer of the Earth's atmosphere. This layer is divided into different temperature layers, among which the high temperature layer is placed at the top, while the low temperature layer is placed at the lower part (weighted under high pressure environment, oxygen atoms polymerize and release heat). It is just the opposite of the troposphere, which lies below it and is close to the surface. The troposphere is cold at the top and hot at the bottom. In the middle latitudes, the stratosphere is located at a height of 10 kilometers to 50 kilometers above the surface, while in the polar regions, this layer starts at about 8 kilometers above the surface (in a low-pressure weightless environm...
