    摘要: 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.

    摘要: Extendable ground arrangement for an antenna system in a radio communication device to be operating at within one or more frequency bands. The ground arrangement includes support means (1), e.g., a slide or flap, carrying conductive ground extension means (4). The support means has fastening means (5) for slidably or rotatably connecting the ground extension means to the radio communication device, wherein the ground extension means is adapted to radiate at at least said first frequency and to couple, e.g., capacitively, to main ground means located in the radio communication device adjacent to said first edge. When extended the extendable ground means provides improved gain and SAR reduction.

    摘要: An RF module having an RF antenna integrated with a RF shielding part is disclosed. The arrangement includes a tuning mechanism for tuning the RF antenna according to a Voltage Standing Wave Ratio (VSWR) specification to thereby tolerate bigger tolerances of the other components on the printed circuit board. More space on the printed circuit board is also obtained as well as avoiding RF losses in transmission lines and soldering connections to an external antenna. A metallic shield can be produced from a single metallic sheet or a molded metallized piece being formed to a desired shape, thereby forming an antenna radiator member integrated with the screening portion of the metallic shield, the antenna radiator member extending over or resting against a supporting element. The VSWR of the antenna radiator member can be tuned by twisting, rotating or shifting the supporting element, which rests on a printed circuit board underlying the antenna device and carrying the electronic components of the RF module.
