This invention refers to an antenna structure for a wireless device comprising a ground plane and an antenna element, wherein the ground plane has the shape of an open loop. The invention further refers to an antenna structure for a wireless device, such as a light switch or a wristsensor or wristwatch, comprising an open loop ground plane having a first end portion and a second end portion, the open loop ground plane defining an opening between the first end portion and the second end portion; and an antenna component positioned within the opening defined between the first end portion and the second end portion and overlapping at least one of the first end portion or the second end portion. Further the invention refers to a corresponding wireless device and to a method for integrating such an antenna structure in a wireless device.

Antenna structure for a wireless device

An antenna includes at least two radiating arm structures made of or limited by a conductor, superconductor or semiconductor material. The two arms are coupled through a region on first and second superconducting arms such that the combined structure forms a small antenna with broadband behavior, multiband behavior or a combination thereof. The coupling between the two radiating arms is obtained via the shape and spatial arrangement thereof, in which at least one portion on each arm is placed in close proximity to each other (e.g., at a distance smaller than 1/10 of the longest free-space operating wavelength) to allow electromagnetic fields in one arm to be transferred to the other through close proximity regions. The proximity regions are spaced from the feeding port of the antenna (e.g., greater than 1/40 of the free-space longest operating wavelength) and specifically exclude the feeding port of the antenna.

Couple multiband antennas

The present invention relates to an integrated circuit package comprising at least one substrate, each substrate including at least one layer, at least one semiconductor die, at least one terminal, and an antenna located in the integrated circuit package, but not on said at least one semiconductor die. The conducting pattern comprises a curve having at least five sections or segments, at least three of the sections or segments being shorter than one-tenth of the longest free-space operating wavelength of the antenna, each of the five sections or segments forming a pair of angles with each adjacent segment or section, wherein the smaller angle of each of the four pairs of angles between sections or segments is less than 180&#xb0; (i.e., no pair of sections or segments define a longer straight segment), wherein at least two of the angles are less than 115&#xb0;, wherein at least two of the angles are not equal, and wherein the curve fits inside a rectangular area the longest edge of which is shorter than one-fifth of the longest free-space operating wavelength of the antenna.

Coupled multiband antennas

A multi-band antenna includes at least one structure useable at multiple frequency ranges. The structure includes at least two levels of detail, with one level of detail making up another level of detail. The levels of detail are composed of closed plane figures bounded by the same number of sides. An interconnection circuit links the multi-band antenna to an input/output connector and incorporates adaptation networks, filters or diplexers. Each of the closed plane figures is linked to at least one other closed plane figure to exchange electromagnetic power. For at least 75% of the closed plane figures, the region or area of contact, intersection, or interconnection between the closed plane figures is less than 50% of their perimeter or area. Not all of the closed plane figures have the same size, and the perimeter of the structure has a different number of sides than its constituent closed plane figures.

A novel loaded antenna is defined in the present invention. The radiating element of the loaded antenna consists of two different parts: a conducting surface and a loading structure. By means of this configuration, the antenna provides a small and multiband performance, and hence it features a similar behavior through different frequency bands.
