摘要:
An antenna (100,200,300, 400, 500) comprising first (110, 210, 310, 410, 430) and second (120, 220, 320, 420, 440) structures for guiding electromagnetic waves, each comprising groups (111, 130, 150, 230, 330; 140,160, 240, 340, 445, 470) of radiation elements. For adjacent sections in 5 the structures, at least one applies: ?Groups of radiation elements are distributed along the two structures such that a group (110, 130, 150) in the first structure overlaps a group (120, 140,160) in the second structure partially or not at all. ?Radiation elements within said groups (230; 240) exhibit a common 10 main direction of extension within the group, and differs between the first and the second groups by an angle of at least 10 degrees. ?The radiation elements of the groups (330, 340) are distributed along the structures (310, 320) on sides of the structures which face different directions.

摘要:
An antenna arrangement comprising at least a first and a second elongated structure, e.g., a coaxial cable, for guiding an electromagnetic wave is provided. Each of said structures comprises a plurality of radiation elements. The structures are positioned alongside each other in their longitudinal direction of extension forming a bundle. The elongated structures are arranged within the bundle such that the radial positions of said structures are alternated in the longitudinal direction of extension.

摘要:
A functional, primary display means comprises a number of first, small pixel elements and comprises or communicates with image generating means for generation of a high resolution miniature image. A main display means comprises a dielectric material which is transparent to radio-, and/or millimeter waves and/or microwaves and comprises a number of second, passive, pixel elements substantially corresponding to, and considerably larger than, the first pixel elements. Each first pixel element is connected to a second pixel element by an optical transmission means for transfer of optical image information. The main display means is adapted to visually represent the transferred optical information as an enlarged image and receiving/transmitting means for communication of radio-, millimeter wave or microwave signals are arranged in or on the main display means such that reception/transmission can take place substantially independently of the optical representation.
摘要:
The present invention relates to an antenna arrangement comprising a constant current electrical loop, which is arranged to provide a first essentially toroid-shaped radiation pattern, where the antenna arrangement further comprises a first and a second electrical dipole. The electrical dipoles are arranged essentially orthogonal to each other, and are arranged to provide a second and third essentially toroid-shaped radiation pattern which each is essentially orthogonal to the other and to the first essentially toroid-shaped radiation pattern. The constant current electrical loop comprises at least two current path parts, where a current can be applied to each one of the parts, so that the current in each one of the parts essentially will be in phase with each other.
