Example embodiments described herein relate to a modular telematics control unit (TCU) with directional Bluetooth Low Energy (BLE) and techniques for using the modular TCU with directional BLE. A modular TCU may include a housing configured to couple to a vehicle and a set of Bluetooth Low Energy (BLE) radios. Each BLE radio is coupled to a corresponding BLE antenna configured for omnidirectional operation. The set of BLE radios and BLE antennas are located within the housing. The modular TCU also includes a heat sink located within the housing and positioned proximate the BLE antennas such that the heat sink limits operation for each BLE antenna to a particular direction extending away from the housing. In some instances, a vehicle computing system may use BLE to detect a device and perform operations based on the location of the device relative to the vehicle.

A backdoor includes a resin outer panel having an opening; a resin inner panel; a metal reinforcement arranged between the outer panel and the inner panel; and a rear glass covering the opening. The rear glass includes a defogger, and an antenna conductor capable of receiving radio waves in an AM band. The antenna conductor includes a power feeding part, and an antenna element having a predetermined length and connected to the power feeding part. The antenna element includes a proximity part extending along an outer edge among upper, lower, left, and right outer edges of the defogger, and having a predetermined spacing from the outer edge. The antenna element is positioned to be separated from the reinforcement by a predetermined spacing, or positioned on a side with respect to the outer edge where the reinforcement is not present in plan view of the rear glass.

A noise reduction structure includes an antenna, a noise source, an electromagnetic conductor, and a grounding member. The antenna has a transmission and reception bandwidth. The noise source radiates an electromagnetic wave. Frequency of the electromagnetic wave falls within the transmission and reception bandwidth. The electromagnetic conductor is closer to the antenna than the noise source. The grounding member is disposed at the noise source in such a manner to face the antenna. The grounding member is electrically isolated from the electromagnetic conductor and forms a good grounding path to the noise source. Furthermore, a transmission dock with the noise reduction structure is provided.
