Mobile radio terminal containing two antenna elements
View Patent ↗The present invention is applied to a mobile radio terminal having an upper body and lower body connected through a hinge mechanism. A first antenna element is disposed near the internal end of the lower body. A second antenna element is disposed between a battery cell within the lower body and the hinge mechanism. The second antenna element has a conductive three-dimensional structure. A radio circuit compares reception levels of the first antenna element and second antenna element and always selects one antenna element having a higher reception level.
1. A mobile radio terminal having an upper body provided with a display portion and lower body connected through a hinge mechanism, the mobile radio terminal comprising:
a first antenna element disposed near the internal lower end of the lower body; and
a second antenna element disposed between a battery cell within the lower body and the hinge mechanism,
wherein the second antenna element has a conductive three-dimensional structure.
2. A mobile radio terminal according to claim 1 , further comprising a switch circuit for comparing reception levels of the first antenna element and second antenna element and selecting one antenna element having a higher reception level.
3. A mobile radio terminal according to claim 2 , wherein the second antenna element is disposed onto the internal rear surface of the lower body.
4. A mobile radio terminal according to claim 3 , wherein an insulating rib is disposed between the second antenna element and the battery cell.
5. A mobile radio terminal according to claim 1 , wherein the second antenna element is disposed onto the internal rear surface of the lower body.
6. A mobile radio terminal according to claim 5 , wherein an insulating rib is disposed between the second antenna element and the battery cell.
