Problems solved by technology

Therefore, the traditional digital board must reserve a boundary area 170 to place part of the antenna loops 110A and 110B that exceed the ground wires 105A and 105B, which limits the size of the tablet and makes it difficult to manufacture a panel with a small boundary area.

Abstract

The multiple antenna loop configuration for electromagnetic inducing system includes several antenna loops and each of the antenna loop has one end contained to an antenna switch and the other end connected to earthing wire. Each of the symmetrical antenna loops has several n-shaped sections to form sawtooth area and constitute several quasi-closed areas. When the symmetrical antenna loops are inphase, the n-shaped sections form the sawtooth area in non-cross mode; and when the symmetrical antenna loops are in phase opposition, the n-shaped sections form the sawtooth area in cross mode.

Description

(1) Technical field [0001] The invention relates to an antenna loop of an electromagnetic induction system, in particular to a layout method of multiple antenna loops of an electromagnetic induction system. (2) Background technology [0002] Since the handwriting recognition circuit device can replace the mouse, and is more suitable for users to input characters and patterns by manual input than the mouse, the improvement of the handwriting recognition circuit device is a rapidly developing field in recent years. Early handwriting recognition circuit devices replaced the mouse with a pen, and in order to improve the user's convenience in operation, the mouse was usually replaced with both a wireless pen and a digital tablet (tablet), and the tip of the wireless pen is usually connected to the mouse. Corresponds to the left button. Although traditional pen input products have been used for many years, similar products only focus on single-function applications such as drawin...
