Under the background, the automobile is used as a mobile carrier, and not only needs to meet the functions of navigation and radio in the traditional sense, but also needs to realize the integration of various modern communication functions.
Modern antennas are moving towards higher integration and smaller size, as are automotive antennas. When the design of the car body model is inconsistent with the space required by the antenna, the space of the antenna is greatly sacrificed to meet the design requirement of the car body. At this time, an antenna product which can meet the communication requirement and does not conflict with the design of the vehicle body is needed. The antenna is mainly a built-in box antenna and integrates different communication functions. Certainly, the signal intensity of the built-in antenna is not as good as that of the traditional shark fin antenna, but the built-in antenna is a good choice under the condition that the space of the antenna is not reserved in the vehicle body, and the problems of high price and space occupation in installation of the external antenna can be solved.
