Embodiment Construction

[0035] Hereby enumerate the preferred embodiment with regard to the structural features and the mode of operation of this case, and cooperate illustration, be described in the following, to provide review and reference.

[0036] The technology described below in the present invention can be applied to devices such as electronic bookcases or electronic lockers. When the antennas on both sides radiate reading signals to the objects with electronic tags in the cabinet, it will be The information of each object in the electronic bookcase can be known through the returned response signal, so as to save the time for the manager to manage or the user to search. For example, in a library with a large collection of books, such technology can play a great role. However, in addition to the above-mentioned implementation manners, the technology of the present invention can also be applied in various fields, which is not limited here.

[0037] Please refer to " image 3 ", revealing the ...

Abstract

A wireless communication device and its method include a first antenna, a second antenna, a signal processing module, and a signal transceiving module. The signal processing module changes the carrier characteristic of the received signal. The signal transceiving module provides an excitation signal to the first antenna and the signal processing module, and receives a response signal returned by the electronic device through the first antenna and the second antenna. The signal processing module includes a first mode for outputting the excitation signal as a first electric wave through the second antenna so as to form a first dark area distribution with the electric wave output by the first antenna, and a signal feature for changing the excitation signal The second antenna outputs the second electric wave so as to form a second pattern of the second dark area distribution that deviates from the first dark area distribution with the electric wave output by the first antenna.

Description

technical field [0001] The present invention relates to a wireless communication device and its method, especially to a wireless communication device and its method that can improve the recognition rate of response signals. Background technique [0002] Radio Frequency Identification (RFID) is a technology for transmitting information through radio waves, and it is mostly applied with a radio frequency identification tag (RFID tag) and a tag reader. The radio frequency identification tag is mainly composed of a chip capable of processing data and a set of transmitting and receiving antennas. It has the advantages of small size, low manufacturing cost, and long service life, so that the radio frequency identification tag can be widely used in various levels. A common application is item management. Specifically, radio frequency identification tags are attached to various objects such as commodities, containers, books, etc. After reading the information of radio frequency ide...
