Description

Technical Field

[0001] The utility model relates to the technical field of satellite navigation, and particularly relates to a narrow-beam RFID circularly polarized antenna. Background Technique

[0002] A narrow-beam RFID circularly polarized antenna is an antenna used in a radio frequency identification (RFID) system, which can transmit or receive radio frequency signals in a specific direction. This kind of antenna is usually used in application scenarios that require directional signal transmission and reception, so as to more effectively identify or track tags, devices or items. For a narrow-beam RFID circularly polarized antenna, "narrow beam" means that the radio frequency signals it transmits or receives are mainly concentrated within a relatively small angular range, which can more accurately locate the target, while "circular polarization" means that the antenna can simultaneously transmit and receive electromagnetic waves rotating along the vertical and horizontal directions, improving the signal transmission quality in complex environments.

[0003] However, when the existing antenna is installed and put into use, the existing one cannot protect the antenna body, which may affect the service life of the antenna. At the same time, the current antenna has poor waterproof and anti-corrosion performance, resulting in a reduced lifespan and affecting the use. Therefore, it is necessary to design a narrow-beam RFID circularly polarized antenna. Summary of the Utility Model

An anti-corrosion coating 10, such as coatings resistant to acids, alkalis, and salt spray, is added on top of the waterproof coating 9 to protect the antenna from the influence of corrosive environments.

When using the device, connecting the connecting wire to the connection port 3 is convenient and practical. After installation, when an object falls on the antenna body 2, the falling object can be blocked through the setting of the protective plate 6. When falling, there is a certain force. At the same time, due to the setting of the spring 5, when the protective plate 6 slides along the column 4, the buffering force can be reduced, thereby protecting the antenna body 2 so that the antenna body 2 will not be severely damaged. First, a waterproof coating 9 is added to the antenna surface to prevent moisture and humidity from invading, improve the water resistance of the antenna, and is suitable for applications in outdoor or humid environments.
