A tire pressure monitoring system used for a vehicle includes a sensor unit, a receiving device, and a control device. The sensor unit is provided at each wheel of the vehicle, detects tire pressure of the each wheel with a tire pressure sensor and transmits data of the detected tire pressure by radio waves. The receiving device includes a receiving antenna that is provided at an outside of the vehicle to receive the data of the tire pressure transmitted from the sensor unit. The control device includes a data acquisition unit that acquires the data of the tire pressure received by the receiving device.

Antenna apparatus includes a dielectric carrier having a first side and a second side. The antenna apparatus also includes a multi-band antenna having an interior surface and an exterior surface. The multi-band antenna includes a first section and a second section that are bent with respect to one another. The interior surface along the first and second sections defines a receiving space. The dielectric carrier is disposed within the receiving space such that the first section is positioned along the first side of the dielectric carrier and the second section is positioned along the second side of the dielectric carrier. The dielectric carrier includes at least one projection that covers a portion of the exterior surface of the multi-band antenna.

A vehicle includes: an antenna; a polarization adjuster configured to change a first polarized wave emitted through the antenna; and a controller configured to receive a wireless signal from a portable user device through the antenna, to identify a second polarized wave emitted from the portable user device based on the wireless signal, and to control the polarization adjuster such that the first polarized wave matches the second polarized wave.

A vehicular parking apparatus includes a frame defining horizontal rows and vertical columns of parking spaces. Subframes are configured to have a vehicle parked thereon and can move vertically in the columns. Platforms move horizontally in the rows and are configured to engage and move the subframes with the vehicles thereon. The subframes, the platforms and the frame provide electrical connections for charging parked electric vehicles.

An antenna module 4 includes one antenna base 25 having a radiation surface 25a inclined relative to an opening plane 23 at which a radome 22 is attached, and another antenna base 25 having a radiation surface 25a inclined in a direction different from the one antenna base 25.

A vision system for a vehicle towing a trailer includes a camera disposed at a rear portion of the trailer and viewing rearward of the trailer. A trailer antenna is disposed at the trailer and in data communication with the camera, and a vehicle antenna is disposed at the vehicle and in data communication with a control unit disposed at the vehicle. The trailer antenna is operable to transmit signals representative of image data captured by the camera toward a road surface along which the vehicle and trailer are traveling so that the transmitted signals reflect off of the road surface and toward the vehicle antenna disposed at the vehicle. The vehicle antenna receives the reflected RF signals and communicates data to the control unit that are representative of the received reflected signals.

A MIMO system is provided for a vehicle having an exterior structure and an enclosure. The system includes external antennas attached to the exterior structure and internal antennas positioned within the enclosure. The system further includes an RF transceiver and an antenna selecting device. The selecting device is disposable between a first state where the selecting device is configured to operably connect at least two of the external antennas to the RF transceiver and a second state where the selecting device is configured to operably connect one or more of the external antennas and one or more of the internal antennas to the RF transceiver. A controller is configured to actuate the selecting device to move to the second state, in response to the signal strength being above an upper strength threshold, and in further response to the ratio being above an upper ratio threshold.

A high frequency antenna carrier in vehicle roof cross member is provided. The antenna carrier is configured to extend width-wise across a vehicle roof to provide structural support for the vehicle roof. The antenna carrier has a lower surface, and a plurality of sidewalls that meet at a common upper flange that mates in a face-to-face relationship with the vehicle roof. The sidewalls may be provided with apertures to facilitate a strong signal passage to and from the high frequency antenna through the carrier. The lower surface of the antenna carrier may be provided with apertures that are aligned with the antennas to improve signal strength.
