Abstract

A terminal includes a metal frame body having: a top frame configured to receive a global positioning system (GPS) antenna; and a middle frame provided with a slot corresponding to the GPS antenna in position, wherein the top frame and the middle frame are electrically isolated from each other by a gap.

Claims

1. An apparatus including a metal frame body, comprising:

a top frame having a global positioning system (GPS) antenna disposed thereon; and

a middle frame provided with a slot corresponding to the GPS antenna in position,

wherein the top frame and the middle frame are electrically isolated from each other by a gap; and

wherein;

the GPS antenna is disposed on an upper portion of the top frame;

the slot has a first end on a first side among four sides of the middle frame;

the first side is adjacent to the gap;

the slot is perpendicular to the first side; and

a projection of the first end on the first side is a projection of the GPS antenna on the first side,

such that an upper hemisphere efficiency for the positioning antenna to receive satellite signals is significantly improved.

2. The apparatus including the metal frame body of claim 1, wherein:

the slot has a first point on a first side of the middle frame;

the slot is perpendicular to the first side; and

the first side is one side adjacent to the gap, among four sides the middle frame.

3. The apparatus including the metal frame body of claim 2, wherein a projection of the first point on the first side is a projection of the GPS antenna on the first side.

4. The apparatus including the metal frame body of claim 1, wherein the slot has a length of m times a signal wavelength of the GPS antenna, m being a numerical value between ⅛

and ½

.

5. The apparatus including the metal frame body of claim 1, wherein:

the top frame and the middle frame are disposed on a same plane; and

the top frame is disposed above the middle frame to facilitate the GPS antenna transmitting or receiving signals.

6. The apparatus including the metal frame body of claim 1, wherein the GPS antenna is disposed on an upper portion of the top frame.

7. The apparatus including the metal frame body of claim 1, wherein the metal frame body is made of at least one of aluminum alloy, aluminum, or anodized aluminum.

8. A terminal comprising the apparatus according to claim 1, comprising:

the metal frame body according to claim 1; and

the GPS antenna.

9. The terminal of claim 8, wherein:

the slot has a first end on a first side among four sides of the middle frame;

the first side is adjacent to the gap; and

the slot is perpendicular to the first side.

10. The terminal of claim 9, wherein a projection of the first end on the first side is a projection of the GPS antenna on the first side.

11. The terminal of claim 8, wherein the slot has a length of m times a signal wavelength of the GPS antenna, m being a numerical value between ⅛

and ½

.

12. The terminal of claim 8, wherein:

the top frame and the middle frame are disposed on the same plane; and

the top frame is disposed above the middle frame to facilitate the GPS antenna transmitting or receiving signals.

13. The terminal of claim 8, wherein the GPS antenna is disposed on an upper portion of the top frame.

14. The terminal of claim 8, wherein the metal frame body is made of at least one of aluminum alloy, aluminum, or anodized aluminum.

15. A mobile terminal comprising:

a positioning antenna;

a metal frame body, comprising;

a top frame having the positioning antenna disposed thereon; and

a middle frame provided with a slot corresponding to the positioning antenna in position,

wherein the top frame and the middle frame are electrically isolated from each other by a gap; and

wherein;

the positioning antenna is disposed on an upper portion of the top frame;

the slot has a first end on a first side among four sides of the middle frame;

the first side is adjacent to the gap;

the slot is perpendicular to the first side; and

a projection of the first end on the first side is a projection of the GPS antenna on the first side,

such that an upper hemisphere efficiency for the positioning antenna to receive satellite signals is significantly improved.

16. The mobile terminal of claim 15, wherein the positioning antenna comprises a global positioning system (GPS) antenna.

17. The mobile terminal of claim 15, wherein the mobile terminal is one of a mobile phone, a tablet computer, or a portable positioning device.

18. The mobile terminal of claim 15, wherein the gap comprises at least one or an air gap or an insulating medium.

19. The mobile terminal of claim 15, wherein the top frame and the bottom frame are removably coupled together.
