Abstract

The invention discloses a simulator for radio frequency identification, which comprises a sending unit which is provided with a first antenna for sending a detecting signal, and a receiving unit which is provided with a second antenna for receiving the detecting signal transmitted by an electronic label, wherein polarization of the first antenna and polarization of the second antenna are orthogonal. The simulator provided by the invention can solve the problem of low receiving and transmitting isolation degree of a simulator in the prior art.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a simulator for radio frequency identification. Background technique [0002] Radio frequency identification technology is a non-contact label information identification transmission technology with a wide range of applications and is considered to be one of the most popular industries in the world in recent years. Its equipment consists of two parts: reader and electronic tag. The data information of the described target object (such as commodities, goods, certificates, etc.) is stored in the electronic tag, and the reader communicates with the electronic tag in a non-contact manner and reads the data therein. Specifically, there is a chip inside the electronic tag, the chip receives the electromagnetic wave sent by the reader, and the chip reflects the received electromagnetic wave according to its own impedance, so as to send the data information of the electronic tag. F...
