Problems solved by technology

[0003] However, the existing three-dimensional antennas all have the problems of complex manufacturing process and high cost, so that the three-dimensional antennas cannot be widely used in electronic equipment. The production of the three-dimensional antenna is time-consuming and labor-intensive, and once it is put into production, if you want to change the appearance of the three-dimensional antenna, you need to change the template, which further increases the cost of the three-dimensional antenna

Abstract

The invention provides a stereo antenna capable of deforming arbitrarily. The stereo antenna comprises a flexible substrate and a coil which is arranged on the flexible substrate. The stereo antenna is connected with a chip. The stereo antenna can be folded into a two-dimensional or three-dimensional structure. Therefore, the stereo antenna can gain more magnetic flux, the card swiping distance is increased in disguised form, and the payment experience is improved.

Description

technical field [0001] The present application relates to antenna technology, in particular to an arbitrarily deformable three-dimensional antenna. Background technique [0002] With the development of wireless communication technology, the application of three-dimensional antennas in the field of mobile payment is becoming more and more extensive. The user swipes the card in any direction, and is no longer limited by the fixed direction of swiping the card. At the same time, since the three-dimensional antenna can be expanded in the entire three-dimensional space, the mobile payment device does not need to reserve a fixed plane area for it. [0003] However, the existing three-dimensional antennas all have the problems of complex manufacturing process and high cost, so that the three-dimensional antennas cannot be widely used in electronic equipment. The production of the three-dimensional antenna is time-consuming and labor-intensive, and once it is put into production, i...
