An antenna system mounted on a vehicle according to the present invention comprises: a first antenna comprising a plurality of conductive members and operating as a radiator in a first frequency band; and a second antenna disposed in the antenna system separate from the first antenna, and operating in a second frequency band higher than the first frequency band. The first antenna may include a loop antenna configured in a loop shape to surround the plurality of conductive members such that signals from the plurality of conductive members are coupled.

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.

A straddle type vehicle comprises a front antenna configured to be capable of transmitting/receiving a wireless signal of a predetermined frequency band and arranged closer to a front side than a seating portion on which a rider can sit, and a rear antenna configured to be capable of transmitting/receiving a wireless signal of a predetermined frequency band and arranged closer to a rear side than the seating portion, the front antenna has directivity in the front side of the straddle type vehicle.

A radar device includes a transmission module and a reception module disposed separately from the transmission module. The transmission module includes: a transmission circuit unit mounted on the first surface of a circuit board; an antenna substrate provided on the second surface side of the circuit board; and a transmission antenna mounted on the second surface of the antenna substrate and not provided in a range on the back surface side of the antenna substrate corresponding to the range in which the circuit board is disposed. The reception module includes: a reception circuit unit mounted on the third surface of a circuit board; an antenna substrate provided on the fourth surface side of the circuit board; and a reception antenna mounted on the fourth surface of the antenna substrate and not provided in a range on the back surface side of the antenna substrate corresponding to the range in which the circuit board is disposed.

A vehicle and vehicle wiper with antenna is directed to improve communication stability with other target vehicles by securing sufficient signal reception sensitivity of an antenna of a vehicle even in rainy weather where the signal reception sensitivity of the antenna may decrease, while at the same time supplementing shortcomings of a short communication distance. A vehicle includes a wiper including a blade for wiping a windshield of the vehicle and an arm for supporting the blade, and a first antenna provided on the arm of the wiper.

A composite antenna device includes a first antenna, plural second antennas whose used frequency bands are different from a used frequency band of the first antenna, and a first conductor portion to serve as a ground plane of the first antenna and the second antennas. Each of the plural second antennas may have a second conductor portion. The first antenna may be provided on the first conductor portion, and at least a portion of the first conductor portion may be positioned between the second conductor portions.

A compact automobile start switch with antenna including a button, a push switch assembly and an antenna assembly module is disclosed. The antenna assembly module is provided with an accommodating cavity in which the push switch assembly is arranged. The antenna assembly module includes an antenna module body, an antenna coil and a connector terminal. The antenna module body is provided with a winding area in which the antenna coil is arranged and a connector matching portion in which the antenna connector terminal is arranged. The antenna connector terminal comprises a connecting section, a fixing section and a terminal welding section and the antenna coil is directly connected with the terminal welding portion by a wire. The antenna coil is directly connected to the antenna connector terminal through the wire outside the antenna module body. The process of connecting the antenna module to the circuit of the PCBA is eliminated.

Provided is an antenna device whose characteristics are enhanced (radio waves are efficiently emitted from an extended antenna) without need to place a communication unit that wirelessly communicates with the outside of a vehicle in close proximity to a loop structure of the vehicle, thus allowing a high flexibility of installation of the communication unit. An antenna device mounted on a vehicle includes a communication unit configured to wirelessly communicate with an outside of the vehicle, and a metal bracket configured to serve also as an extended antenna, and the communication unit includes a housing and a substrate-accommodated in the housing and on which a pattern antenna is formed, the metal bracket includes a first part fixed to the housing and a second part fixed to the vehicle.

An antenna device includes a ground plate and an antenna element. The ground plate is a conductor member with a flat rectangular shape. The antenna element is a conductor member having a feed point electrically connected to a feeder line. A length of the ground plate in a predetermined direction is shorter than a target wavelength that is a wavelength of a radio wave to be transmitted or received. The ground plate is connected to a grounding cable at a connection position on the ground plate. The connection position is shifted from an edge of the ground plate by an odd multiple of ¼ of the target wavelength.

A wireless communication system includes a first wireless communication device installed on an installation surface of a vehicle and a second wireless communication device. The first wireless communication device includes an antenna and a sensor. The antenna includes a first conductor, a second conductor, one or more third conductors, a fourth conductor, and a feeding line. The first wireless communication device transmits a signal from the antenna to the second wireless communication device, based on information detected by the sensor.
