Description
Technical field
The present invention relates to a kind of antenna loop configuration of EM induction system, particularly relate to a kind of EM induction system antenna loop configuration that can integrate with other input units.
Background technology
Generally speaking, the antenna loop of traditional electromagnetic induction device and layout designs thereof are that antenna loop equidistantly is arranged in grid network with X, Y-axis array, with the induced electricity magnetic pen with calculate its absolute coordinate.Antenna loop configuration with reference to the X-axis shown in Figure 1A, every day, the end of line loop 110A connected a switch (X1 to X7) respectively, and its other end is connected with a ground wire 105A respectively, and by this, the signal that every day, line loop 110A responded to can detect via the control to switch X0 to X4.Because magnetic field intensity and square distance are inversely proportional to, when the time writer of emission electromagnetic field is more far away apart from antenna, can make that the received signal of antenna loop is more faint; Relatively, when the time writer of emission electromagnetic field is more near apart from antenna, can make that the received signal of antenna is more strong.Therefore, as long as allow the microprocessor all antenna loops of P-SCAN one by one of digiboard, and analyze the received signal power of each antenna loop, be positioned at the scope of that strip antenna just can learn time writer, and then calculate its position coordinates.
See also shown in Figure 1B, it is depicted as the antenna loop configuration of Y-axis, the antenna loop configuration of Y-axis, same, wherein every day line loop 110B an end connect a switch (Y1 to Y7) respectively, and its other end is connected with a ground wire 105B respectively, and by this, the signal that every day, line loop 110B responded to can detect via the control to switch Y0 to Y4.The antenna loop configuration difference of the antenna loop configuration of Y-axis and X-axis only at it along the disalignment layout.The layout that then comprises X-axis antenna loop (shown in Figure 1A) and Y-axis antenna loop (shown in Figure 1B) shown in Fig. 1 C for tradition.
Yet, because now to the multi-functional requirement of electronic product, digiboard or electromagnetic induction device no longer are confined to single function of electromagnetic induction and input pattern, but further go in conjunction with more various input unit, by its most popular touch-control device now, the capacitive sensing layout of projection-type or matrix form for example, and make digiboard or electromagnetic induction device can be combined inductive mode and the function with diversification with touch-control device.
Yet, because the antenna loop of the electromagnetic induction device of traditional type is the layout (with reference to Figure 1A and Figure 1B) of an alternating expression, therefore, influence induction for avoiding antenna to contact with each other, must make perforation 102A or 102B in the staggered position of each antenna and other antennas, carry out layout and this antenna is extended other layers by perforation 102A or 102B.With Figure 1A wherein an antenna loop be that example is illustrated, connect the antenna loop of switch X2 owing to will avoid contacting with the antenna loop of switch X1, therefore, the place that interlocks at the antenna loop with switch X1 need make a perforation 102A, the antenna loop of switch X2 is directed to a plane different with the plane, antenna loop place of switch X1, though make it it seems it is staggered with the antenna loop of switch X1 by vertical view, but in fact be because it extends to different planes via perforation 102A and does not contact with the antenna loop of switch X1, and other antenna loop also is principle setting according to this among the figure.
The layout type of this antenna loop is at the electromagnetic induction device of simple function, because it is made on the rigid or soft circuit board, so though the step of layout is more loaded down with trivial details, there is no too big difficulty in the making of perforation and antenna loop.Yet, if will be in conjunction with other touch induction installations, then antenna loop must be made on the employed base material of touch induction installation, but the difference because of its material and circuit board, and make that making numerous tiny perforation like this at base material is very difficult and difficult making, increases the difficulty of its combination and reduces its possibility.Therefore, need badly and want a kind of antenna loop configuration that does not need to make the electromagnetic induction device of perforation, can be integrated in same base material or the medium with the touch induction installation, and make a multi-functional input unit.
