Problems solved by technology

However, the use of metal enclosures creates new challenges for radio frequency (RF) antenna implementation
Common prior art antenna solutions such as coupled antennas with radiator elements in conductive loop structures perform poorly in all cases e.g. due to the inherent directivity of their radiation pattern

Embodiment Construction

[0031] exist figure 1 An assembly 10 of the present invention for an antenna operating in slot mode is shown in . Exemplary components include a circuit board (PCB) 12 for a device such as a sports watch or a smart watch, and a body, such as an annular bezel 11 , made of conductive material and arranged on and parallel to the PCB 12 . A gap of distance D between the PCB 12 and the annular bezel 11 defines a slot that enables the assembly 10 to act as an antenna in slot mode. The periphery of the PCB 12 is at least partially aligned with the outer shape of the bezel 11, and has a metal layer along at least a part of the periphery (see image 3 , item 33), this metal layer is connected to the ground plane of the PCB 12 .

[0032] Obviously, the frame can take the shape of, for example, a circle, an ellipse, a square, a rectangle or any other polygon. The shape of the PCB then needs to be designed accordingly.

[0033] figure 1 The exemplary assembly in also includes a feed ...

Abstract

The invention concerns an assembly for an antenna operating in a slot mode. It is also directed to an electronic wristwatch-like device comprising such antennas. The antenna assembly comprises at least one circuit board of an electronic device, a conductive body arranged at a distance from said at least one circuit board and defining a slot between them, at least one feed element for coupling an electromagnetic signal between said conductive body and said circuit board. A length of the slot is defined between two points at which said conductive body is connected to a ground plane of said at least one circuit board.

The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyright rights. technical field [0003] The present disclosure generally relates to antenna devices for use in electronic devices such as wireless or portable radio devices, and more particularly in devices using slot antennas. Background technique [0004] Antennas are commonly found in most modern radio devices, such as mobile computers, portable navigation devices, mobile phones, smartphones, personal digital assistants (PDAs), wrist watches or other personal communication devices (PCDs). Typically, these antennas include a planar radiating element with a ground plane that is generally parallel to the planar radiating elem...
