Benefits of technology

[0011]One of objects of the invention is to provide a wireless device having a touch panel, capable of preventing deterioration in the characteristic of an antenna.

Problems solved by technology

However, any attempts to use the touch panel in small wireless devices such as mobile phones will face various challenges.
Thus, if such line approaches the antenna, there is concern it will have an unfavorable influence on a characteristic of the antenna (for example, a decrease of impedance, electromagnetic interference, etc.).
Thus, disposing the entire antenna in a position overlapped with the substrate may cause unfavorable issues in the light of the characteristic of the antenna described above.

first embodiment

[0029]A first embodiment of the invention will be described herein below, with reference to FIG. 1 to FIG. 6. FIG. 1 is a perspective view illustrating an appearance of a wireless device 1 related to the first embodiment of the invention. The wireless device 1 includes a touch panel 11 at a front (a face facing the user during use) of the casing 10 having a rectangular shape with a thickness (the rectangular shape includes a shape similar to a rectangle with rounded corners, as shown). The touch panel 11 is configured to overlap, for example, a liquid crystal display device with a touch sensor made of a transparent material, which will be described later. The touch panel 11 is used as an operation input unit by displaying software-controlled operation keys on a screen of the display device, and used as a display unit capable of displaying various texts or images.

[0030]FIG. 2 is a front view illustrating main configurations of the wireless device 1 when viewed from the front (i.e., f...

second embodiment

[0053]Next, a second embodiment of the invention will be described with reference to FIGS. 7 to 12. For simplicity, description of configurations similar to the wireless device 1 related to the first embodiment shown in FIGS. 1 to 5 will be omitted. Each configuration of the wireless device 5 related to the second embodiment of the invention, other than the elements of the wireless device 1, will be described hereinafter.

[0054]FIG. 7 is a front view illustrating the main configurations of the wireless device 5 related to a second embodiment of the invention when viewed from the front of the paper as in FIG. 2. The wireless device 5 includes the display 52 in the front of the casing 50. For the wireless device 5, a first feeding point 61 and a second feeding point 62 are mounted at the upper part of the casing 50 in FIG. 7, and a first antenna element 71 and a second antenna element 72 respectively connected to the feeding points are built in the casing 50.

[0055]As shown in FIG. 7, t...

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The entire disclosure of Japanese Patent Application No. 2009-082341 filed on Mar. 30, 2009, including specification, claims, drawings and abstract is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Field of the Invention[0003]One aspect of the invention relates to a wireless device, in particular, to a wireless device including a touch panel configured by a display device and a touch sensor.[0004]2. Description of the Related Art[0005]A touch panel configured by combining a touch sensor and a display device such as a liquid crystal panel is used as an operation input means for various electronic devices, for example, mobile phones, handheld terminals, copiers, portable game machines, electronic dictionaries, car navigators, electric appliances, automatic ticket vending machines, cash dispensers, etc.).[0006]In such a touch panel, since the operation keys displayed on a screen of the display device can be set up variou...
