An antenna mounting device is provided for a motor vehicle. That antenna mounting device includes a body having a first mounting end with a first cross section and a second mounting end with a second, different cross section. In addition, the antenna mounting device includes an antenna anchor point carried on the body and adapted to receive and hold an antenna. The two mounting sections allow versatility in mounting the antenna mounting device in different structures carried on the motor vehicle including, for example, a stake pocket and a trailer hitch receiver.

A sensing system for a vehicle includes a radar sensor unit disposed at the vehicle so as to sense exterior of the vehicle. The radar sensor unit includes a radar housing that houses a radar sensor and associated circuitry. The radar sensor unit includes an outer element configured to correspond with an outer surface of a component of the vehicle at location where the radar sensor unit is disposed. The outer element includes a radome material and reduces attenuation of electromagnetic signals emitted by and received by the radar sensor as compared to attenuation of electromagnetic signals of the component of the vehicle.

The present invention includes: a film antenna (10); a cable (20) which is connected to a feed section (14) of the film antenna (10); and a support (30) around which at least part of the film antenna (20) is wound, the support (30) including a holding section for holding the cable (20).

An millimeter wave antenna includes an antenna body adapted to transmit and receive an electromagnetic wave of a millimeter wave band; and a radome that covers a transmitting and receiving surface of the antenna body. The transmitting and receiving surface and the radorm are apart from each other and have a space therebetween. The radome includes a gap adapted to allow the electromagnetic wave of the millimeter wave band to pass through the gap. A radar apparatus for vehicle includes the millimeter wave antenna.

In one aspect, a scooter is provided. The scooter may include a steering column. The scooter may include a rider-support-platform coupled to the steering column. The scooter may include an antenna attached to the steering column. The antenna may be configured to perform wireless communication. The antenna may have a first inclination angle relative to the steering column. In another aspect, a method of providing a scooter is provided. The method may include providing a steering column of the scooter. The method may include coupling a rider-support-platform to the steering column. The method may include attaching an antenna to the steering column.

A vehicle radar inspection system and method are provided for inspecting a mounting state of a radar sensor mounted to a vehicle. The vehicle radar inspection system includes a centering portion that aligns a position of the vehicle by driving rollers, displacement sensors that are respectively disposed at front and rear sides of the centering portion, an array antenna that measures propagation intensity of a radar signal transmitted from the radar sensor, and a server that connects wireless communication with a wireless terminal of the vehicle, calculates a mounting position of the radar sensor, and detects a mounting error of the radar sensor with reference to a normal reference mounting specification.

An antenna mounting bracket assembly for coupling an antenna to a vehicle includes a first plate, a bar, and a coupler. A set of apertures positioned in the first plate is configured to be aligned with hinge holes positioned in an upper hinge. Hinge bolts are insertable through the apertures, the hinge holes, and holes positioned in a door frame of the vehicle so that the first plate is coupled to the vehicle. A spacer is coupled to and extends from a first face of the first plate. The bar is coupled to and extends from the spacer distal from the first plate so that the bar extends between the door frame and a door when the door is closed. The coupler is coupled to the bar distal from the spacer and is configured to couple to a mount of an antenna to couple the antenna to the vehicle.

Licence plates with a data medium and a slot antenna have low transmission and reception performance for electromagnetic waves as a rule. Moreover, the positioning of the slot antenna is severely limited by an inscription on the licence plate. The invention provides a licence plate with a data medium and an antenna with improved transmission power and at the same time sufficient space for the positioning of the antenna. This is achieved by a licence plate body of the licence plate having at least one cavity, and a front of the licence plate body or a coating of the front of the licence plate body covering the cavity comprises a slot structure forming the antenna.

A radar sensing system for a vehicle includes a radar sensor disposed at the vehicle so as to have a field of sensing exterior of the vehicle. The radar sensor includes a plurality of transmitters that transmit radio signals, a plurality of receivers that receive radio signals, and a plurality of antennas that communicate the radio signals to the receivers and from the transmitters. The received radio signals are transmitted radio signals that are reflected from an object. A processor is operable to process outputs of the receivers to detect the object. At least some of the antennas of the radar sensor include non-rectangular slot antennas each having a slot that includes a longitudinal portion and a transverse portion that extends transverse in at least one direction from the longitudinal portion. The non-rectangular slot provides an enhanced radiation pattern of the transmitted radio signals.

Multi-input downconversion mixers, systems, and methods are provided with input switching in the intermediate frequency or baseband domain. One illustrative mixer embodiment includes: multiple differential pairs of transistors and multiple pairs of switches. Each differential transistor pair has their bases or gates driven by a differential reference signal, their emitters or sources connected to a common node having a current or voltage driven based on a respective one of multiple receive signals, and their collectors or drains providing a product of the differential reference signal with the respective one of the multiple receive signals. Each of the switch pairs selectively couples differential output nodes to the collectors or drains of a respective one of the multiple differential pairs, enabling the differential output nodes to convey an output signal that is a sum of products from selected ones of the multiple differential pairs.
