Problems solved by technology

[0011] If the antenna is installed on the outside of the ground pattern, the size of the insulating substrate will increase, which in turn will increase the size of the input device.
In addition, if the width of the ground pattern is wide and there is a ground pattern near the antenna, the electromagnetic wave and magnetic flux generated by the antenna will be reflected or absorbed by the ground pattern, resulting in a decrease in communication performance.

no. 1 approach

[0070] figure 1 A notebook personal computer (electronic device) 11 equipped with the input device 10 with an antenna according to the first embodiment is shown. The computer 11 has a main unit 12 and a display 14, and the main unit 12 and the display 14 are connected via a screen hinge. The display 14 turns from a state (closed state) overlaid on the main body 12 which is normally placed flat, to a state (open state) standing relative to the main body 12 by rotating around the screen axis.

[0071] The display 14 has, for example, a display case 16 made of resin. The display case 16 is formed in the shape of a flat box, and has a size approximately equal to, for example, A4 paper. The display case 16 has a surface (inner surface) facing the main unit 12 in the closed state, and an opening is formed on the inner surface of the display case 16 over substantially the entire area. On the opening 16 a of the display case 16 , for example, a liquid crystal panel 18 is exposed. ...

Abstract

An antenna embedded input device includes an insulating substrate disposed along a sensing surface, measurement electrodes provided in the insulating substrate and detecting a touch of an object on the sensing surface, an antenna provided in the insulating substrate so as to surround the measurement electrodes and transmitting or receiving a balanced signal, a grounding terminal provided in the insulating substrate, and a grounding conductor connecting an electric midpoint of the antenna to the grounding terminal.

Description

technical field [0001] The present invention relates to an input device with an antenna and electronic equipment equipped with the device. Background technique [0002] As a touch input device, for example, a touch panel input device is mounted on electronic equipment such as a notebook type personal computer (notebook computer). In a notebook computer, a main unit having a keyboard and a display are connected through a screen hinge, and in the main unit, a touch panel input device is disposed on the operator's side of the keyboard. [0003] In a notebook computer, a shielding member is provided inside the housing of the host. The shielding member is provided so as to cover the electronic equipment inside the main body, thereby suppressing radiation or incidence of unnecessary electromagnetic waves (EMI countermeasures: Electro-Magnetic Interference). [0004] However, an opening for arranging the touch panel input device is provided on the housing of the main body and the...
