Abstract: This application discloses example radio frequency identification systems and example methods for constructing a relay network, a reader, and a repeater. One example radio frequency identification system includes a reader, a repeater, and a target tag. The reader can be configured to send a first signal to the repeater. The repeater can be configured to send an excitation signal to the target tag based on the first signal. The target tag can be configured to send a target backscatter signal based on excitation of the excitation signal, where the target backscatter signal carries electronic product code information. The reader can be further configured to receive the target backscatter signal and obtain the electronic product code information in the target backscatter signal.

Abstract: The antenna in the embodiments provided includes: a first-layer antenna, a second-layer antenna, a first probe, a second probe, a first connector, and a second connector. An annular microstrip patch is attached to each of main bodies of the first-layer antenna and the second-layer antenna. The annular microstrip patch attached to the first-layer antenna is provided with a first feeding network and a second feeding network therein. The first-layer antenna is connected to the first probe and the second probe by using the first feeding network and the second feeding network respectively. The first-layer antenna is connected to the first connector and the second connector. A position of the first connector corresponds to a position where the first probe is connected to the first-layer antenna. A position of the second connector corresponds to a position where the second probe is connected to the first-layer antenna.
