Abstract: Disclosed is a lens antenna comprising a dielectric lens consisting of a collimating part and an extension part, and an antenna element. The extension part of the lens comprises a substantially flat surface crossed by the axis of the collimating part, and the antenna element is rigidly fixed on the surface. The antenna element is formed by a hollow waveguide and comprises a dielectric insert with one end thereof adjacent to said surface; the size of the radiating opening of the waveguide is determined by the predefined width of the main beam and by side lobe levels of the radiation pattern of the lens antenna. The technical result of the invention is an increase in realized gain value due to the use of a waveguide antenna element with a dielectric insert, which provides impedance matching in a wide frequency bandwidth. The present invention can be used in radio-relay point-to-point communication systems, e.g.

Abstract: Disclosed is a system for data collection and data transfer from a vehicle, the system comprising at least one data collecting device provided in or on the vehicle, at least one data recording and storage device provided in or on the vehicle and connected to the at least one data collecting device, at least one first wireless communication device provided in or on the vehicle and connected to the at least one data recording and storage device, and at least one second wireless communication device located outside the vehicle, wherein the first and second wireless communication devices are capable of establishing a wireless connection therebetween providing high throughput for data reception and transmission, wherein the at least one first and the at least one second wireless communication devices each contain an antenna with a narrow radiation pattern beam.
