Product Description
Product Description
As the key component of vehicle-mounted signal reception, the installation position of automobile Car Antenna is unique. The rear windshield, the side windshield and the front windshield may all become the "shelter" of the antenna. Among them, the design of printing metal wires on the front windshield skillfully transforms the glass into the antenna carrier.
In the attack of FM/AM vehicle antenna performance optimization, engineers face the technical problems of limited Car Radio Antenna space and poor signal sensitivity, and make a breakthrough by combining front-end amplification and link optimization: by embedding a low-noise amplifier, the weak signal in the 30MHz-108MHz frequency band is directionally enhanced by more than 15dB. At the same time, the adaptive LC matching circuit is used to dynamically calibrate the transmission impedance of AM(530-1710kHz) and FM(87.5-108MHz) bands, and the standing wave ratio is stably controlled within 1.3:1, which improves the signal transmission efficiency by over 30%, successfully overcomes the reception problems in weak signal scenes such as underground garages and mountainous areas, and makes the sound quality of car-mounted broadcasting clearer and smoother.
The research and development of automobile FM AM Antenna is undergoing a revolutionary leap from "trial and error exploration" to "digital intelligence innovation". With the help of cutting-edge technologies such as electromagnetic simulation (MoM/FDTD algorithm) and finite element analysis (FEM), engineers can build a high-precision antenna model in virtual environment, accurately simulate key parameters such as radiation pattern and impedance matching characteristics, and shorten the traditional physical verification cycle by more than 60%. The deep integration of theoretical design methods not only improves the prediction accuracy of antenna gain, bandwidth and other core performance parameters to 92%, but also realizes the optimal solution of antenna structure and function through multi-objective optimization means such as genetic algorithm (GA) and particle swarm optimization (PSO), which promotes the iterative efficiency of product performance by nearly three times.
As the core hub of in-vehicle communication, automobile FM and AM antenna supports multi-scene applications with strong compatibility: it is not only the "sound entrance" of AM/FM broadcasting, but also provides users with real-time news and music entertainment; More deeply integrated into the Intelligent Transportation System (VICS) to achieve millisecond reception of road information; At the same time, it supports FM multiplexing technology to transmit text information and audio content synchronously; In the field of vehicle multimedia, it also undertakes the functions of TV signal reception, Bluetooth telephone connection and so on, and even becomes a signal relay station for intelligent key, remote control and other equipment, and becomes a key infrastructure for intelligent upgrading of automobiles.
