A vehicle is provided that comprises two or more radio frequency (RF) antennas and two or more RF transceivers to communicate wirelessly sensitive information associated with a user of the vehicle (the two or more RF antennas being at different physical locations on an exterior of the vehicle). The vehicle determines which one of the two or more RF antennas is receiving a strongest signal from a common signal source, selects a first RF transceiver associated with the RF antenna with the strongest signal to send the sensitive information associated with the user to the common signal source, and sends the sensitive information associated with the user to the first RF transceiver for transmission to the common signal source.

A vehicle antenna system having high transmission and reception efficiency is provided. A vehicle antenna system includes an antenna that is attached to a vehicle and is capable of transmitting and receiving radio waves of a predetermined frequency band. The antenna is attached to the vehicle in such a way that an elevation angle of the antenna with respect to a horizontal plane becomes large in a predetermined angle range in accordance with the height of a communication frequency band.

A mount system, such as for a vehicle antenna, includes a module with a ground. A fastener extends into the module. A retainer clip moves from an undeployed position to a deployed position by operation of the fastener. The fastener extends through a deployment ramp block. The deployment ramp block engages and guides the retainer clip from the undeployed position to the deployed position, by operation of the fastener. The mount system is configured to effect grounding of the ground to the product and to retain the module in position on the product.

An antenna suitable for use in the 5 GHz WLAN/Wi-Fi and DSRC frequency band is integrated with a vehicle window that is includes outer and inner transparent plies bonded together by an interlayer. The inner transparent ply and the interlayer serve as an antenna substrate. A first conductive layer is formed on the inner surface of the outer transparent ply and a second conductive layer that defines a coupling slot is formed on the outer surface of the inner transparent ply. The antenna may be excited by a coaxial cable or a microstrip line that crosses the coupling slot.

Exemplary embodiments are disclosed of vehicular systems including distributed active antennas, adaptive cellphone evolution (e.g., via a smartphone, mobile device, user equipment, etc.) and/or integrated access and backhaul. In exemplary embodiments, a distributed antenna system includes a central unit onboard a vehicle. The central unit includes a transceiver configured to operate in a cellular network. The central unit also includes an analog to digital converter/digital to analog converter coupled to the transceiver. Four active antennas are onboard the vehicle. Each active antenna includes an analog to digital converter/digital to analog converter and is configured to communicate with the central unit digitally. A link connects each of the active antennas to the central unit. The link is configured to transmit signals digitally and support at least 10 Gbps of bandwidth between the central unit and the active antennas.

Provided is a glass antenna having an improved circularly polarized wave reception bandwidth in a frequency range from 1 to 2 GHz. The glass antenna has a core-side feeding part, a ground-side feeding part arranged adjacent to the core-side feeding part, a first element extending from the ground-side feeding part, and a parasitic element including a first wire, a second wire arranged parallel or substantially parallel to the first wire and a third wire connecting the first and second wires. The parasitic element is disposed to surround the core-side and ground-side feeding parts between an edge of a metal body part adjacent to the core-side and ground-side feeding parts and the third wire. A blank portion is provided between the parasitic element and the first element such that the parasitic element and the first element allow resonance with a radio wave in any arbitrary frequency band within the frequency range.

An antenna system for vehicles includes a first antenna attached in a vicinity of a windshield of a vehicle; and a second antenna attached in a vicinity of a rear glass of the vehicle, wherein the first antenna and the second antenna are configured to transmit and receive an electromagnetic wave in a predetermined frequency band F, and wherein defining a region A and a region B with respect to a vehicle center axis extending in a traveling direction of the vehicle, so as to bisect a vehicle width of the vehicle from a viewpoint in a direction normal to a horizontal plane, the first antenna is arranged in the region A, and the second antenna is arranged in the region B.

Radar loss caused by a windshield having laminated glass in a vehicle is suppressed with a simple configuration. An antenna's radiation section is disposed inside the windshield of a vehicle having a plurality of layers. The radiation section not only radiates radio waves but also receives reflected waves of the radio waves from a target. A distance measurement information generation section is connected to the radiation section. The distance measurement information generation section measures a distance to the target on the basis of the radiated radio waves and the reflected waves from the target and generates distance measurement information.

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.

A gladhand assembly includes a gladhand that rotates about a first axis with respect to a sealed housing. The sealed housing includes a lever affixed to the first axis to rotate as the gladhand rotates. A stop within the sealed housing may be configured into an engaged position in which it engages with the lever to lock the gladhand into a fixed position in which the gladhand cannot be rotated about the first axis. In addition, the stop may be configured into a retracted position to permit the lever to rotate and allow the gladhand to be rotated into a deployed position.
