An antenna device configured to be attached to a vehicle includes: an antenna of a resonance type; and a matching circuit connected to the antenna, wherein the matching circuit includes a first matching circuit connected to a feeding portion of the antenna and a second matching circuit connected to a subsequent stage of the first matching circuit, wherein the first matching circuit reduces an impedance in a frequency band that is away to a higher-frequency range or a lower-frequency range from a resonance point of the antenna such that the impedance is lower than before connection of the first matching circuit, and the second matching circuit increases an impedance in a vicinity of the resonance point of the antenna such that the impedance is higher than before connection of the second matching circuit.

A ceiling enclosure that includes a main body, swing down panel and enclosure door. There are pivot ear retention legs extending from the main body. There are latch pin legs extending from the main body. The swing down panel is adapted to mount devices to the swing down panel. The swing down panel includes pivot ears extending from the swing down panel to attach to pivot ear retention legs and includes latch pin retention legs extending from the swing down panel to attach to latch pin legs.

A radio frequency (RF) antenna assembly is mounted on a shielded panel to facilitate the transmission of RF signals therethrough. The RF antenna assembly includes an RF antenna formed from wire which is bent to define first and second antenna elements. The RF antenna is inserted through the panel with the first and second antenna elements disposed on opposite sides thereof. A dome-shaped cap constructed of a compressible elastomeric material is mounted over the first antenna element and lies flush against the outer surface of the panel. A disc-shaped dielectric base receives the distal end of the second antenna element and lies flush against the inner surface of the panel. The RF antenna exerts a spring-like force that resiliently draws the cap and base together. In use, each antenna element transmits RF signals within a designated frequency range to wireless electronic devices located on the same side of the panel.

A roof antenna includes a base plate, an outer cover, an inner cover arranged under the outer cover and connected to the base plate, and a fastening device on the base plate arranging and fastening the roof antenna at an intended installation location. The inner cover accommodates at least one antenna element for receiving and/or transmitting high-frequency signals that is arranged on the base plate. The roof antenna includes a camera arranged under the outer cover and accommodated inside the inner cover. At least one of the outer cover and the inner cover has an opening for a recording field of the camera.

Provided is an antenna device includes a base connector fixed to a support substrate, a module connector connected to the base connector to the base connector, and an antenna module fixed to the module connector and configured to transmit or receive a radio wave. The base connector includes a base-side casing, a base-side fitting portion, and multiple base-side terminals. The module connector includes a module-side casing, a module-side fitting portion, and a multiple module-side terminals. The antenna module includes an antenna substrate and an antenna element provided on a front surface of the antenna substrate. In a state in which the base connector is fixed to the support substrate and the module connector is connected to the base connector, the antenna module is fixed to the module-side casing such that the front surface of the antenna substrate faces up diagonally to the outside of the module connector.

A vehicle antenna mounting system, including an antenna circuit board, an antenna base supporting the antenna circuit board, an antenna cover covering the antenna circuit board, and a temporary mounting member temporarily mounting the antenna base on a roof of a vehicle body. The antenna base has a mounting projection protruding downwardly from a bottom surface of the antenna base and a cavity defined in the mounting projection. The temporary mounting member is received in the cavity and the roof has a hole into which the temporary mounting member is inserted.

Telemedicine systems and methods are described. In a telemedicine system operable to communicate with a remote operations center, communications can be transmitted/received using a transceiver having an antenna. The antenna can include first and second di-pole antenna elements, the first di-pole antenna element being vertically polarized and the second di-pole antenna element being horizontally polarized. A controller of the system can establish, using the transceiver, a telemedicine session with the operations center using a Transport Morphing Protocol (TMP), the TMP being an acknowledgement-based user datagram protocol. The controller can also mask one or more transient network degradations to increase resiliency of the telemedicine session. The telemedicine system can include a 2D and 3D carotid Doppler and transcranial Doppler and/or other diagnostic devices, and provides for real-time connectivity and communication between medical personnel in an emergency vehicle and a receiving hospital for immediate diagnosis and treatment to a patient in need.

An antenna adapter which can be mounted to the roof of a vehicle equipped with an Original Equipment Manufacturer (OEM) roof-mounted “shark fin” antenna comprises a spacer having a generally oblong body that is at least as large as the footprint of the OEM antenna with a mounting surface that extends beyond the footprint of the OEM antenna. The mounting surface is adapted to receive an antenna base while the underside of the adapter includes an oblong recess for routing an antenna cable from the antenna base to the interior of the vehicle. The adapter is mounted to the vehicle roof using a threaded fastener that is longer than the OEM fastener. The adapter is sandwiched between the OEM antenna and the vehicle roof to provide a leakproof seal.

An antenna sealing plug for a flexible antenna interconnect device includes a sealing surface extending around the antenna sealing plug in a circumferential direction and sealing a feed-through of a vehicle that leads into the vehicle, and a slot-like passage. A feedthrough portion of the flexible antenna interconnect device can be guided through the feed-through of the vehicle. The feedthrough portion of the flexible antenna interconnect device can be guided through the slot-like passage of the antenna sealing plug in a sealing manner.

A roof antenna for a vehicle has a cover that is connected to a baseplate via a latching unit. The latching unit comprises latching hooks that releasably engage behind elastic latching lugs.
