Abstract

A wearable device including a display unit, a conductive frame and a belt-like structure is provided. The conductive frame surrounds a display region of the display unit, and the conductive frame has a first open slot. Besides, a feeding point and a first ground point are disposed on two sides of an opening of the first open slot, and the conductive frame forms a first antenna element. The belt-like structure is respectively connected to a first edge and a second edge, which are opposite to each other, of the conductive frame.

First claim

What is claimed is:

1. A wearable device, comprising:
a display unit;
a conductive frame, having a first open slot, wherein a feeding point and a first ground point are disposed at two sides of an opening of the first open slot, and the conductive frame forms a first antenna element and comprises:
a frame body, surrounding a display region of the display unit, wherein an edge of the frame body has the feeding point; and
a first extension element, wherein one end of the first extension element is electrically connected to the edge of the frame body, another end of the first extension element has the first ground point, and the first extension element and the edge of the frame body form the first open slot; and
a belt-like structure, respectively connected to a first edge and a second edge of the conductive frame, the first edge and the second edge being opposite to each other.

2. The wearable device as claimed in claim 1 , wherein a size of the first open slot is related to impedance matching of the first antenna element.

3. The wearable device as claimed in claim 1 , wherein the conductive frame further comprises a second open slot, and the wearable device further comprises:
a microstrip line, opposite to the second open slot and having a second ground point, wherein the microstrip line and the conductive frame form a second antenna element.

4. The wearable device as claimed in claim 3 , wherein a size of the second open slot is related to impedance matching of the second antenna element.

5. The wearable device as claimed in claim 1 , wherein a shape of the first extension element is an L shape.

6. The wearable device as claimed in claim 1 , wherein the conductive frame further comprises:
a second extension element, electrically connected to the first extension element, wherein the second extension element, the first extension element, and the edge of the frame body form a second open slot.

7. The wearable device as claimed in claim 6 , wherein the first extension element and the second extension element form an inverted T shape.

8. The wearable device as claimed in claim 6 , wherein the wearable device further comprises:
a microstrip line, opposite to the second open slot and electrically connected to the second extension element through a second ground point, wherein the microstrip line and the conductive frame foam a second antenna element.

9. The wearable device as claimed in claim 1 , further comprising:
a first connecting element, disposed between the belt-like structure and the first edge of the conductive frame; and
a second connecting element, disposed between the belt-like structure and the second edge of the conductive frame.

10. The wearable device as claimed in claim 1 , wherein the conductive frame is a part of a housing of the wearable device.

11. The wearable device as claimed in claim 1 , wherein the display unit is a liquid crystal display, and the conductive frame is disposed in a conductive film layer of the liquid crystal display.

12. The wearable device as claimed in claim 1 , wherein the wearable device is a smart watch.

13. A wearable device, comprising:
a display unit;
a conductive frame, surrounding a display region of the display unit and having a first open slot and a second open slot, wherein a feeding point and a first ground point are disposed at two sides of an opening of the first open slot, and the conductive frame forms a first antenna element;
a microstrip line, opposite to the second open slot and having a second ground point, wherein the microstrip line and the conductive frame form a second antenna element; and
a belt-like structure, respectively connected to a first edge and a second edge of the conductive frame, the first edge and the second edge being opposite to each other.

14. A wearable device, comprising:
a display unit;
a conductive frame, surrounding a display region of the display unit and having a first open slot, wherein a feeding point and a first ground point are disposed at two sides of an opening of the first open slot, and the conductive frame forms a first antenna element;
a belt-like structure, respectively connected to a first edge and a second edge of the conductive frame, the first edge and the second edge being opposite to each other;
a first connecting element, disposed between the belt-like structure and the first edge of the conductive frame; and
a second connecting element, disposed between the belt-like structure and the second edge of the conductive frame.
