This study intends to fabricate a small-size capacitive wireless transmission device. As to the design of electrode plates, the active electrode is designed in two ways, through row array and column array, and the area of an electrode plate is limited to below 20.25 cm2. Moreover, the passive electrode of row-Array electrode plates is designed in three ways: general row array, window array, and rhombus array. As seen from the results of circuit simulation, the transmission efficiency of the capacitive wireless transmission device is as high as 0.7. In the actual circuit experiment, the electrode plate in the window-Array design has the highest efficiency at 51%. In addition, the electrode plates in the window array and those in other arrays have higher stability and transmission efficiency. In the rotational angle dislocation experiment, the unit area current amount of the column-Array electrode plates in the high coupling region is also smaller than that of the window-Array electrode plates. However, the performance of column-Array electrode plates reaches higher stability in the angle dislocation experiment, and its anti-Angle dislocation is obviously higher than that of the electrode plates designed in the other three row arrays. Moreover, when the area of the column-Array electrode plates is 22.25 cm2, the highest transmission distance is 22.5 mm.
