Abstract

An antenna, comprising a primary radiation patch antenna, a first printed circuit board (PCB) substrate, a coaxial radio-frequency excitation port and a floor, wherein the primary radiation patch antenna is arranged at one side of the first PCB substrate, and is connected to the coaxial radio-frequency excitation port in the first PCB substrate; the coaxial radio-frequency excitation port is provided on the first PCB substrate, and one side of the first PCB substrate is provided with the primary radiation patch antenna, and the other side thereof is provided with the floor; and the primary radiation patch antenna is composed of one or more fractal structures. The antenna in the present invention can be applied to an RFID system of a small-scale terminal, and satisfies the reliability of the RFID system, thereby satisfying the potential demand of the current development and the future development of the RFID technology.

Description

technical field [0001] The invention relates to the technical field of near-field communication, in particular to an antenna applied to an RFID system. Background technique [0002] Radio Frequency Identification (RFID, Radio Frequency Identification) is a wireless communication technology that began to rise in the 1990s and gradually matured. It uses radio frequency signals to conduct non-contact two-way communication, automatically identify target objects and obtain relevant information data. RFID uses radio frequency signals to achieve contactless information transmission through spatial coupling, and achieves the purpose of identification through the transmitted information. The key component of the RFID system is the antenna, and the key to the practical application of RFID technology also depends on the design of the antenna. The antenna is one of the key factors affecting the reliability and other performance of the wireless communication system. It is very importan...
