Antenna assembly with aluminum base and electromagnetic barrier
A recently granted patent (Publication Number: US11764463B2) describes an antenna assembly and a wireless communication assembly for vehicles. The antenna assembly includes a base made of aluminum material, with a modem placed inside the base on heat dissipation elements. The top lid of the base has antenna elements on its exterior surface. A housing covers the top lid and the base, with specific dimensions ranging from 50 to 90 millimeters in height and 2 to 7 millimeters in wall thickness. A communication cable connects the modem to a vehicle internal router, allowing the modem to be located closer to the antenna elements. The assembly also includes a combiner for 5G communication.
The patent claims that the top lid and the base act as an electromagnetic barrier for the modem, providing protection and reducing interference. By connecting the modem to the vehicle internal router through a communication cable, the modem can be placed remotely from the router and closer to the antenna elements. This arrangement minimizes the connection length between the antenna elements and the modem, potentially improving signal strength and performance.
In addition, the patent mentions that the base can be composed of die-cast aluminum material, which may offer advantages in terms of durability and heat dissipation. The dimensions of the base range from 2.5 to 3.5 inches in width, 6.0 to 8.0 inches in length, and 0.5 to 1.0 inch in height.
The wireless communication assembly described in the patent is similar to the antenna assembly, with the inclusion of a modem placed on heat dissipation elements within the base. The assembly also features a top lid with antenna elements, a housing with specific dimensions, a communication cable connecting the modem to a vehicle internal router, and a combiner for 5G communication.
Overall, this patent presents an antenna assembly and a wireless communication assembly designed for vehicles. The use of aluminum material, specific dimensions, and the arrangement of the modem and antenna elements aim to improve signal strength, reduce interference, and optimize performance in wireless communication for vehicles.
