Kilometer-level pressure-resistant and waterproof antenna without shell

Abstract

A kilometer-level pressure-resistant and waterproof antenna without a shell belongs to the technical field of a communication antenna. The kilometer-level pressure-resistant and waterproof antenna comprises a metal base, a substrate, a circuit board and an antenna, wherein the metal base is connected with the substrate, a component groove is formed in the top of the substrate, a base line hole isformed in the center, corresponding to a substrate line hole, of the metal base, a part, corresponding to the component groove, of the circuit board is arranged at the top of the substrate, a base rodis arranged at the top of the circuit board, the base rod, the circuit board and the substrate are fixedly connected, an antenna groove is further formed in an outer wall of the base rod, the antennais connected to the circuit board and extends to the top of the base rod along the corresponding antenna groove, a shielding cable is arranged at the bottom of the circuit board and extends to the bottom of the metal base, and a waterproof coating layer is arranged at outer sides of the base rod and the substrate. The conflict between pressure-resistant capability and communication signal attenuation caused by the adoption of a hard pressure-resistant shell of an existing antenna is solved, the production cost is low, signal stability is ensured, meanwhile, a better pressure-resistant effectcan be achieved by an internal pressure bearing mode, the antenna can be effectively adaptive to an underwater kilometer-level environment, and the practicability is greatly improved.

Description

technical field [0001] The invention relates to a kilometer-level pressure-resistant waterproof antenna without a shell, which belongs to the technical field of communication antennas. Background technique [0002] At present, satellite antennas are usually used in related equipment of the global positioning system or satellite communication system, and are also an essential component of marine operation equipment or platforms with real-time or quasi-real-time data satellite communication transmission capabilities and global positioning capabilities. Since the ocean is a three-dimensional space, marine operation equipment or platforms not only need to perform satellite communication or positioning on the sea surface, but also need to dive underwater. During this process, the satellite antenna will also dive into the water with the equipment or platform, which requires the satellite antenna to have a certain waterproof and pressure resistance capability to ensure that the ant...

AI Technical Summary

Problems solved by technology

Although the antenna improves the anti-impact and anti-mechanical fatigue ability of the antenna to a certain extent, it does not solve the contradiction between the pressure resistance ability of the hard shell and the signal strength and quality of the satellite communication.

As the water pressure rises, there is still a risk of damage to the shell structure. At the same time, the stability of the cable groove is not high. bending fatigue damage
