Abstract

A mobile radio terminal in which a miniature antenna is integrated or spatially arranged with a camera lens. The mobile radio terminal includes a housing having a microphone, a speaker, a display, a keypad which might be optional if the display is touch-sensitive, and a camera. The antenna is arranged around a camera lens as an antenna-lens-assembly inside the housing in order to minimize space consumption, decrease hand-interference and minimize antenna losses.

Claims

1. A mobile radio terminal comprising:

a camera means for image capturing;

a compact antenna-lens-assembly comprising;

an optical camera lens means configured for optically directing an image into said mobile radio terminal for image capturing by said camera means, and

at least one antenna for communication of said mobile radio terminal,

said antenna being circumferentially positioned on or around a circumferential side wall of the optical camera lens means.

2. The mobile radio terminal according to claim 1, wherein said optical camera lens means is arranged inside a housing of said mobile radio terminal.

3. The mobile radio terminal according to claim 1, wherein said optical camera lens means comprises a generally cylindrical lens body having two ends and said circumferential side wall.

4. The mobile radio terminal according to claim 1, wherein said antenna is positioned in close vicinity around said circumferential side wall.

5. The mobile radio terminal according to claim 1, wherein said antenna is integrated into said circumferential side wall.

6. The mobile radio terminal according to claim 1, wherein said antenna operates in the frequency range from 800 MHz to 6000 MHz.

7. The mobile radio terminal according to claim 1, wherein said antenna is of spiral or helical form.

8. The mobile radio terminal according to claim 7, wherein said antenna comprises a feeding pin and a grounding pin.

9. The mobile radio terminal according to claim 7, wherein said spiral or helical form has a helix trace of about a quarter wavelength of a desired operating frequency of said antenna.

10. The mobile radio terminal according to claim 1, wherein said antenna has a metallic trace printed or etched on said side wall of said lens body.

11. The mobile radio terminal according to claim 1, wherein said antenna is attached to a carrier.

12. The mobile radio terminal according to claim 11, wherein said carrier is a flex-film or a rigid carrier.

13. The mobile radio terminal according to claim 11, wherein said antenna is attached to the carrier by printing or etching and/or pasting.

14. The mobile radio terminal according to claim 11, wherein said antenna attached to the carrier is arranged around said side wall of said lens body.

15. The mobile radio terminal according to claim 14 wherein said lens body is in the form of a cylinder.

16. The mobile radio terminal according to claim 1, wherein said antenna is a multi-band antenna.

17. The mobile radio terminal according to claim 1, wherein said lens is of low microwave loss material.

18. The mobile radio terminal according to claim 17, wherein said low microwave loss material is plastic or glass.

19. The mobile radio terminal according to claim 1, wherein said antenna is a monopole or a multipole antenna and has a single branch or multiple-branches and consists of a mono-layer or multiple layers.

20. The mobile radio terminal according to claim 1, whereby said mobile radio terminal is a mobile telephone.
