Benefits of technology
This patent discusses using coil units to extend the distance and adjust the direction of reading through magnetic coupling. This helps to improve the efficiency and accuracy of reading, as it reduces the chances of errors or mistakes. Thus, this patent aims to provide a solution for extending the reading distance and improving the accuracy of magnetic coupling.
Problems solved by technology
Moreover, in a situation where the RF reader reads a RE tag with a three-dimensional shape, when the RF tag with a three-dimensional shape passes through the space in the antenna of the RF reader, passing time in the readable range of the antenna may be too short to successfully read the RF tag.
Or, if the RF tag passes through the antenna of the RF reader along a direction of a reading dead space, the RF tag will not be able to acquire enough energy for operation.
Because the direction of the RF tag is unchangeable at the moment, the RF reader loses data of the RF tag.

Abstract
An electronic device includes a reader and a plurality of first coil units. The reader is configured to read at least one wireless signal. The reader is connected to a first coil unit of the first coil units to read the wireless signal in an original reading distance. Other first coil unit(s) of the first coil units is separately arranged in an order started from the first coil unit. Spacing between any two of the first coil units is lower than or equal to the original reading distance. The first coil units are configured to generate magnetic coupling with an adjacent first coil unit started from the first coil unit to extend the original reading distance as a first extended reading distance and adjust a direction of the first extended reading distance.
Description
RELATED APPLICATIONS[0001]The present application is a Divisional Application of the U.S. application Ser. No. 15 / 210,907, filed Jul. 15, 2016, which claims priority to U.S. Provisional Application Ser. No. 62 / 193,093, filed Jul. 16, 2015, Taiwanese Application Serial Number 104136042, filed Nov. 2, 2015, and Japanese Application Serial Number 2016-085508, filed Apr. 21, 2016, all of which are herein incorporated by reference.BACKGROUNDTechnical Field[0002]The present invention relates to a wireless communication technology. More particularly, the present invention relates to a device for adjusting orientation of magnetic field and a device for extending and expanding operational range of a radio frequency tag.Description of Related Art[0003]In present radio frequency (RE) technology for wireless reading, a readable range of a RE tag by a RF reader with a single antenna is a circular magnetic field or an elliptical magnetic field around the antenna. If a read position of the RF tag ...
