Lightweight and foldable microwave and laser hybrid thin-film communication antenna

Abstract

The invention discloses a light foldable microwave and laser-mixed film communication antenna, which belongs to the technical field of wireless communication. In order to solve problems existing in the prior art, the inner side of a microwave reflector is connected with the outer side of a first round metal ring; an optical primary mirror is arranged between the first round metal ring and a second round metal ring; a piezoelectric sheet is attached to the back surface of the optical primary mirror; one ends of three trusses are uniformly distributed on the first round metal ring, the other ends support an optical secondary mirror, a microwave feed source is arranged above the optical secondary mirror, and the microwave feed source is arranged below a casing; the center of the casing is arranged on a casing shaft, and the casing shaft is located above the microwave feed source; one ends of seven supporting frames are arranged on the round metal ring, and the other ends are used for fixing the lower end surface of the casing; one ends of seven foldable metal ribs are arranged on positions, the same as the supporting frames, on the round metal ring; one ends of seven connection rods are connected onto the middle positions of the seven foldable metal ribs, and the other ends are connected onto the middle positions of the supporting frames respectively; and the microwave feed source is located at the focus of the microwave reflector.

Description

technical field [0001] The invention relates to a wireless communication antenna, in particular to a foldable microwave and laser hybrid film communication antenna, which belongs to the technical field of wireless communication. Background technique [0002] Laser wireless communication is a very important communication method in the field of wireless communication because of its advantages such as large communication capacity, high transmission rate, good confidentiality, strong anti-electromagnetic interference ability, light weight, small size, and low power consumption. However, when the laser passes through the atmosphere, a series of atmospheric effects such as atmospheric absorption, scattering and turbulence have a great impact on the signal transmission of the laser wireless communication system, especially the effect of dense fog and thick clouds on the laser. The microwave radio frequency signal is less affected in the atmosphere, which makes up for the defects of...
