摘要： Provided is an antenna system comprising a board with an antenna configured to radiate power, and a housing surrounding the board to protect the board from an environment. Herein the housing comprises an opening with at least one metallic wall extending towards the board, wherein the at least one metallic wall is configured to redirect the power radiated by the antenna into a predetermined system radiation direction in a predetermined radiation pattern. This antenna system makes use of an appropriate antenna distribution and of a design of a housing with a de- /reflecting feature that reinforce radiated waves to re- direct the radiated power and/or to modify the radiation pattern. As a result, coverage of signal among longer distance can be achieved without the use of antennas with larger aperture allowing further miniaturizing of the entire antenna system.

摘要： An antenna comprises at least one half-slot antenna element 12 arranged in a recess, where the recess provides a ground plane wall 16 for the said at least one half-slot antenna element 12. The slot antenna element may be a half-Vivaldi antenna element. Also disclosed is an antenna which comprises at least one antenna element 12 arranged in a recess, where the recess provides a ground plane for the said at least one antenna element and the antenna element 12 comprises a conductive plate arranged perpendicular to the mouth 20 of the recess and is spaced from a wall 16 of the recess to provide a slot 14 between the edge 6 of the conductive plate and the wall 16 of the recess. Further disclosed is an antenna comprising a common ground plane and a plurality of antenna elements 12, where each antenna element comprises a conductive plate arranged perpendicular to the common ground plane and where the edge 6 of each antenna element plate is spaced from the ground plane to provide a slot 14 between the edge 6 of the conductive plate and the common ground plane. The recess may be a tapering polyhedral cone-like formation with linear and/or curved wall portions and a closed end 22 and open end 20 formed by a 3D-printer. The antenna may be used in telecommunication systems.

摘要： A mounting unit (210) securely mounts a radio wave reflection device (200) on a stable installation place such as a pole (20). A reflector unit (300) holds two reflectors (350, 360) at a tilt angle of 45°, allowing the two reflectors (350, 360) to be coaxial and rotatable independently of each other. A joint unit (220) connects the reflector unit (300) and the mounting unit (210). The joint unit (220) has rotational freedom along two axes (AZ axis and EL axis) orthogonal to each other. A radio wave reflecting device that relays, by reflection, radio communications between a first antenna device and a second antenna device distant from each other is thereby provided.

摘要： A structure and a method for modifying an existing design of structure are provided, wherein the structure is provided to at least partially enclose an object that has a large radar cross section. The structure comprises a non-metallic portion having a radar-reflective layer applied to an inclined surface of the structure. The inclined surface is arranged with one or more angles of inclination selected so that the radar cross-section for the structure has a value that is lower than that for the object enclosed in one or more frequency ranges. In a preferred variation, an at least partially detached and appropriately shaped radar-reflective structure may be provided as an alternative to or to supplement the modification of an existing enclosure.

摘要： The essence of the invention consists of the particular geometry of the reflectors or dispersers which constitute the anti-radar chaff cloud. Instead of using conventional rectilinear forms, in the present invention multilevel and space-filling forms are introduced. Due to this geometric design, the properties of the radar chaff clouds improve mainly in two aspects: radar cross-section (RCS) and mean time of suspension.
