Description

Technical Field

[0001] The present application relates to the field of vehicle-mounted navigation technology, and in particular to an active antenna for a vehicle-mounted navigation GPS device. Background Art

[0002] With the continuous development of the automobile industry and the increasing demand for travel convenience, in-vehicle navigation equipment has been widely used in modern vehicles. As a satellite system that provides global positioning, navigation and timing services, the Global Positioning System (GPS) has become one of the core technologies of in-vehicle navigation equipment. In order to ensure that navigation equipment can stably receive GPS signals in various complex environments, the design and performance of the antenna are crucial. Traditional passive antennas rely on the power provided by external receivers to process signals and are easily affected by noise and interference. Especially in environments with severe signal shielding such as urban high-rise buildings or mountains, the signal reception effect is poor. Active antennas, as an advanced antenna technology, are increasingly used in in-vehicle navigation equipment. Active antennas integrate low-noise amplifiers (LNA) inside, which can amplify the signal as soon as it is received, thereby improving the signal strength and signal-to-noise ratio, and significantly enhancing the reception performance.

[0003] At present, after the active antenna is connected to the interface of the car, the signal end of the active antenna needs to be placed on the roof or body of the car to locate the position of the car, and the connecting wire generally needs to pass through the gap between the car bodies. If the connecting wire is not limited, the connecting wire will continue to shake, causing wear and tear, and the continuous shaking will also generate noise. Therefore, an active antenna for a car-mounted navigation GPS device is designed. Utility Model Content
