Abstract

A slot antenna and an information terminal apparatus using the same are provided. The slot antenna comprises: a conductive housing; and at least one slot formed on the corner and edge of the conductive housing.

First claim

What is claimed is:

1. A slot antenna, comprising:
a conductive housing including a bottom and sidewalls extending from the bottom;
a main slot disposed at a corner at which two sidewalls meet and including two or more slot segments that are interconnected, wherein a first segment of the main slot is formed on the bottom of the conductive housing and extends along the two sidewalls of the conductive housing meeting near the corner, and wherein a second segment of the main slot is formed on one of the two sidewalls and extends parallel to the first segment; and
at least one parasitic slot located adjacent to the main slot and separated from the main slot.

2. The slot antenna of claim 1 , wherein the first segment of the main slot is formed at a first edge at which the bottom meets a first sidewall of the two sidewalls and a second edge at which the bottom meets a second sidewall of the two sidewalls.

3. The slot antenna of claim 2 , wherein an end of the second segment of the main slot extends to an end of the conductive housing and is open.

4. The slot antenna of claim 1 , wherein an end of the parasitic slot extends to an end of the conductive housing and is open.

5. An information terminal apparatus, comprising:
a display panel;
a conductive housing including a bottom and sidewalls extending from the bottom configured to surround sides and a back of the display panel;
a main slot disposed at a corner at which two sidewalls meet and including two or more slot segments that are interconnected, wherein a first segment of the main slot is formed on the bottom of the conductive housing and extends along the two sidewalls of the conductive housing meeting near the corner, and wherein a second segment of the main slot is formed on one of the two sidewalls and extends parallel to the first segment; and
at least one parasitic slot located adjacent to the main slot and separated from the main slot.

6. The information terminal apparatus of claim 5 , wherein the main slot does not overlap the display panel with respect to a direction normal to the display panel.

7. The information terminal apparatus of claim 5 , wherein the first segment of the main slot is formed at an edge at which the bottom meets a first sidewall of the two sidewalls and an edge at which the bottom meets a second sidewall of the two sidewalls.

8. The information terminal apparatus of claim 7 , wherein an end of the second segment of the main slot extends to an end of the conductive housing and is open.

9. The information terminal apparatus of claim 5 , wherein an end of the parasitic slot extends to an end of the conductive housing and is open.

10. The information terminal apparatus of claim 5 , wherein the parasitic slot do not overlap the display panel with respect to a direction normal to the display panel.
