Three-dimensional slot antenna

1. A three-dimensional slot antenna comprising:

a loop conductor having a first side, a second side opposite to said first side, and a third side extending between said first and second sides;

a first conductor arm including a first radiator section and a first connecting section interconnecting said first radiator section and said first side of said loop conductor;

a second conductor arm including a second radiator section connected to said third side of said loop conductor; and

a third conductor arm including a third radiator section and a third connecting section interconnecting said third radiator section and said second side of said loop conductor;

wherein said first radiator section, said second radiator section and said third radiator section are disposed on a same plane,

said second radiator section cooperating with said first and third radiator sections to form a first slot segment,

said first radiator section further cooperating with said third radiator section to form a second slot segment,

said first and second slot segments forming a substantially T-shaped slot.

2. The three-dimensional slot antenna as claimed in claim 1 , wherein said loop conductor, said first conductor arm, said second conductor arm, and said third conductor arm are formed integrally.

3. The three-dimensional slot antenna as claimed in claim 2 , wherein:

said first conductor arm is bent from said loop conductor along a first fold line,

said second radiator section is bent from said loop conductor along a second fold line,

said third conductor arm is bent from said loop conductor along a third fold line,

said loop conductor includes a first conductor part to which said first, second and third conductor arms are connected, and a second conductor part bent from said first conductor part along a fourth fold line,

said first, second, and third conductor arms and said loop conductor cooperating to form a substantially box-shaped structure.

4. The three-dimensional slot antenna as claimed in claim 3 , further comprising a support member disposed in said box-shaped structure, said first radiator section, said second radiator section and said third radiator section being disposed on a same surface of said support member.

5. The three-dimensional slot antenna as claimed in claim 4 , further comprising a transmission line having a signal terminal and a grounding terminal, said loop conductor further including a feed-in part connected to said first conductor part and said signal terminal, and a grounding part connected to said second conductor part and said grounding terminal.

6. The three-dimensional slot antenna as claimed in claim 1 , further comprising a transmission line having a signal terminal and a grounding terminal, said loop conductor further including a feed-in part connected to said signal terminal, and a grounding part connected to said grounding terminal.

7. The three-dimensional slot antenna as claimed in claim 6 , which is operable to resonate in Wireless Local Area Network (WLAN) and World Interoperability for Microwave Access (WiMAX) frequency bands.

8. The three-dimensional slot antenna as claimed in claim 1 , which is operable to resonate in WLAN and WiMAX frequency bands.

9. The three-dimensional slot antenna as claimed in claim 2 , which is operable to resonate in WLAN and WiMAX frequency bands.

10. The three-dimensional slot antenna as claimed in claim 3 , which is operable to resonate in WLAN and WiMAX frequency bands.

11. The three-dimensional slot antenna as claimed in claim 4 , which is operable to resonate in WLAN and WiMAX frequency bands.
