V2X is an important application of the Internet of Things in the driving situation of vehicles. Security protection is the main application at this stage.
V2X brings the eyes of the super-distance, which is an important part of the necessary technology for automatic driving and intelligent transportation. V2X is a general name for V2V (VehicletoVehicle car communication), V2I (VehicletoInstrucTIon car communication), V2P (VehicletoPedestrian), etc. V2X can obtain a series of traffic information such as real-time road conditions, road information, pedestrian information, etc., thus bringing long-distance environmental signals. .

Active safety: With the V2X car network, the vehicle can acquire the unknown parameters of the surrounding environment and the running status of the nearby vehicles. Then the vehicle-side active safety algorithm will process the acquired information and classify the information according to the priority, which may cause danger. The situation is pre-warned, and in the emergency situation, the vehicle's execution end can be used to control the vehicle to avoid risks.

Over-distance video transmission: By installing a camera in the pedestrian gathering area, the road test node is sent out to the vehicle node to remind the passing vehicle. In this way, the driver knows the situation ahead as early as possible in the high-incidence area of ​​the accident, and adopts the appropriate speed to improve the travel safety.

Traffic signal transmission: At present, the driver can only obtain the traffic sign by visual inspection, which not only increases the burden on the driver, but also causes a traffic accident or traffic violation due to the short interval between the identification of the indicator and the action taken. With the V2X car network, commands such as road speed limit, limit line, and signal lights can be transmitted to the vehicle terminal. The vehicle terminal can remind the driver according to the information or assist the driver through the execution end.

Improve driving safety & reduce operating costs, commercial vehicles have a higher demand for V2X car networking than passenger cars
Commercial vehicles not only need to improve the safety of driving, but also need to balance operational efficiency. V2X technology can be used as an ADAS function module to reduce the accident rate of commercial vehicles. It can also build intelligent fleets, build formations, plan routes, reduce fuel consumption and improve operational efficiency. At present, German companies have carried out commercial vehicle V2X experiments with satisfactory results.

With the rapid development of mobile communication equipment, in the mobile communications network engineering design, according to the requirements of the network coverage, traffic distribution, anti-interference requirements and network service quality and so on the actual situation to select the base station antenna, the communication base station antenna is currently on the market work the characteristics of the narrow frequency band, such as directional literal outdoor antenna, The operating frequency band is 860~960Mhz. Those multi-band antennas have the characteristics of high manufacturing cost and complex structure. With the development of communication technology, especially the popularization of 3G communication technology, such antennas are difficult to meet the market requirements. Therefore, to avoid the above problems, it is necessary to provide a base station antenna that is simple to manufacture, low cost, and reliable in performance to overcome the alleged defects in prior art.
