Wireless device

Abstract

A wireless device includes: a casing having a first face; a display configured to be visible from the first face; a touch sensor formed by a transparent material and mounted in the casing with respect to the display as a part of the first face; a substrate mounted to a side opposite to the first face with respect to the display; and an antenna element including: a first portion built in the casing, connected to a feeding point included in the substrate, and located within a first range occupied by the touch sensor when viewed from a direction perpendicular to the first face; and a second portion located within a second range other than the first range.

1 . A wireless device comprising:
 a casing having a first face;   a display configured to be visible from the first face;   a touch sensor formed by a transparent material and mounted in the casing with respect to the display as a part of the first face;   a substrate mounted to a side opposite to the first face with respect to the display; and   an antenna element including:
 a first portion built in the casing, connected to a feeding point included in the substrate, and located within a first range occupied by the touch sensor when viewed from a direction perpendicular to the first face; and 
 a second portion located within a second range other than the first range. 
   
     
     
         2 . The wireless device of  claim 1 , wherein:
 current of a relatively large amplitude is distributed at the first portion when power is fed, and   voltage of a relatively large amplitude is distributed at the second portion when power is fed.   
     
     
         3 . The wireless device of  claim 1 , wherein
 the antenna element includes a portion extending from the feeding point in a direction away from the first face.   
     
     
         4 . The wireless device of  claim 1 , comprising a conductive member arranged between the first portion of the antenna element and the touch sensor. 
     
     
         5 . The wireless device of  claim 1 , wherein
 the antenna element includes an open-ended monopole antenna, a folded monopole antenna, and an inverted-F antenna.   
     
     
         6 . The wireless device of  claim 1 , wherein:
 the first face has a shape of a rectangle, and   the antenna element is mounted in a vicinity of one short side of the rectangle.   
     
     
         7 . The wireless device of  claim 6 , further comprising an antenna element mounted in the vicinity of the one short side of the rectangle. 
     
     
         8 . The wireless device of  claim 6 , further comprising an antenna element mounted in a vicinity of the other short side of the rectangle. 
     
     
         9 . A wireless device comprising:
 a casing having a first face;   a touch panel including a display and a touch sensor, the touch panel being a part of the first face;   a substrate in the casing; and   an antenna element in the casing including:
 a first portion connected to a feeding point included in the substrate, and located within a first range occupied by the touch panel when viewed from a direction perpendicular to the first face; and 
 a second portion located within a second range other than the first range. 
   
     
     
         10 . The wireless device of  claim 9 , wherein:
 current of a relatively large amplitude is distributed at the first portion when power is fed, and   voltage of a relatively large amplitude is distributed at the second portion when power is fed.   
     
     
         11 . The wireless device of  claim 9 , wherein
 the antenna element includes a portion extending from the feeding point in a direction away from the first face.   
     
     
         12 . The wireless device of  claim 9 , comprising a conductive member arranged between the first portion of the antenna element and the touch panel. 
     
     
         13 . The wireless device of  claim 9 , wherein
 the antenna element includes an open-ended monopole antenna, a folded monopole antenna, and an inverted-F antenna.   
     
     
         14 . The wireless device of  claim 9 , wherein:
 the first face has a shape of a rectangle, and   the antenna element is mounted in a vicinity of one short side of the rectangle.   
     
     
         15 . The wireless device of  claim 14 , further comprising an antenna element mounted in the vicinity of the one short side of the rectangle. 
     
     
         16 . The wireless device of  claim 14 , further comprising an antenna element mounted in a vicinity of the other short side of the rectangle.
