Harman's in-car 5G antenna design can simultaneously solve the problems of antenna distribution, placement, and heat dissipation. 
The automotive digital ecosystem is gradually taking shape. Harman predicts that the first in-vehicle 5G networking system will be on the road in mid-2021, which can expand in-vehicle applications and experience, and various automakers will also announce the deployment schedule to strengthen competitiveness and satisfaction Consumers demand and profit from it, only to properly solve the antenna distribution and placement issues.

According to a report from Digital Trends, in-car 5G enables in-car Infotainment to be as versatile as smartphones or tablets, and supports advanced in-car games such as virtual reality (VR), high-resolution video streaming, and a large selection of apps Such as value-creating experiences. In addition, the software update of the vehicle no longer needs to be returned to the dealer, and the OTA method can be adopted like a smart phone or NB.

5G is also expected to vigorously promote the cellular Internet of Vehicles (C-V2X) to become a killer application. Decentralized data processing methods such as Edge Computing have great potential and can greatly reduce the need to transmit to the central data. The amount of data in the database, for example, when a road is blocked, when updating a road condition map, only need to transmit the data to all vehicles within a radius of about 2 miles, instead of transmitting to the United States or the world and occupying bandwidth, which can reduce transmission costs and time.

The frequency band used by 5G transmits signals over a short distance, so establishing a reliable connection requires more hardware support. For example, many antennas are required to transmit a large amount of data, but this is very difficult to integrate seamlessly with vehicles. Harman, a US company under Samsung Electronics, specializes in the development of electronics and connected products. BMW announced at the 2020 Consumer Electronics Show (CES 2020) that Harman will be the mass production version of the connected electric SUV expected to be launched in 2021. Provide in-car 5G networking solutions.

Apple's first-generation iPhone made the antenna embedded in the phone case without being exposed, and strengthened the signal to penetrate metal or plastic. Harman's researchers applied this to 5G car antennas to support 5G communication in the car. The antenna is fixed in a single structure and becomes a conformal antenna that allows the vehicle to maintain the original appearance design. A single structure can accommodate up to 14 antennas. It can be installed under a thin metal plate such as the roof panel to solve the antenna distribution and placement problems at the same time.

However, using a single structure is not a panacea. Since it is usually installed above the rear seat between the roof panel and the roof, heat dissipation is a big problem, especially when exposed to the sun, the antenna itself works The heat generated also needs to be dissipated. Therefore, the 5G parts used by Harman must meet stricter standards than other connected devices such as mobile phones. Harman's in-vehicle 5G networking system is expected to be launched between 2021 and 2023.
