摘要:
The main object of the present invention is to provide a wide band antenna device integrated in a vehicle (101) for receiving and transmitting RF signals, without transmitting electromagnetic radiation into the compartment of the vehicle. This is achieved by providing a housing (104) being transparent to RF radiation in at least one direction. The housing being arranged inside the compartment (105) of the vehicle. The housing comprising means for suppressing RF radiation in substantially all directions facing substantially inwards the compartment of the motor vehicle seen from a radiating element (201) being arranged in the housing.

An antenna means for transmitting and/or receiving RF signals, a radio communication system and a method for manufacturing a radiating structure. The antenna means comprises a conductive structure (10) extending between first and second opposite edges (11, 12), and a feed portion. The conductive structure (10) is formed to a radiating structure (1) partially enclosing a volume, and the first and second edges (11, 12) are located at a distance from each other forming a radiating first slit (21), which has a first and a second open end. Hereby an antenna means, which can be made compact, and can operate in more than one frequency band is obtained. A second slit can be arranged to improve the operation in a higher frequency band. The radio communication system comprises transmitting/receiving circuits connected to an such antenna means.
摘要:
The present invention relates to an antenna means for transmitting and/or receiving RF-signals in at least a first frequency band. The antenna means comprising a ground plane means (20) arranged to be connected to ground of a circuitry of a radio communication device, a conductive radiating structure (10) having a first end (12) and a second end (14), were said conductive radiating structure (10) being separated from the ground plane means (20). Said first end (12) being connected to ground end said second end (14) being a feed portion.

An antenna means (2) for transmitting and receiving RF signals, comprising: a ground plane (11) arranged to be connected to ground of the circuitry of a radio communication device and a conductive radiating structure (20) in the form of a band. The radiating structure has in a first end a feed portion (21) arranged to be coupled to circuitry of a radio communication device. The radiating structure has a second end which is a free end (29). The band has a first (A) and a second (B) surface, and is divided by bent portions into a number of sections Sn along its length. The band is bent or folded so that the first surface (A) of a first section S1 faces the first surface (A) of a second section S2, being adjacent to the first section S1, and the second surface (B) of a section Sm faces the second surface (B) of a consecutive section Sm+1, whereby a compact antenna means which can operate within a wide frequency band is achieved.

The present invention relates to an antenna unit (10) for mounting on a mounting surface from a first side of the mounting surface. The antenna unit (10) comprises an element (12) comprising a first side (14) abutting against the mounting surface when the antenna unit (10) is mounted, and a second side (16) arranged parallel to and opposite the first side (14). The antenna unit (10) comprises an antenna mount (18) comprising an attachment member (22) in turn comprising a threaded hole (20) in which a bolt member (24) is applied. The bolt member (24) is manipulated by a tool (26) from the first side of the mounting surface. In a first end position of the attachment member (22), the same is applicable through a hole intended therefor in the mounting surface. In a second end position, when the bolt member (24) has been tightened by the tool (26), the attachment member (22) presses/clamps the antenna unit (10) against the first side of the mounting surface.
