A Design Of Dual Microstrip Antenna UHF RFID Attendance System

RFID technology is a widely used non-contact long distance communication technolo-gy, which combines electromagneticfield theory,the wireless signal transceiver technology, integrated circuit technology, and data encoding and decoding technology. It has numbers of advantages such as transmission speed, long distance and high security.RFID technology-has occupied the mainstream market of wireless identification system.In the second genera-tion ID card,electronic ticketing,public transportation,property management and many other fields, radio frequency identification technology has been widely used.Attendance system is a major application of radio frequency identification technology. In achieving attendance system, the non-contact card has become a mainstream way of atten-dance. However, in practical application, it is still unable to achieve automatic attendance in this way, such as it can not statistical work long, not support long-range identification, relatively low efficiency, accuracy, and low defects on the many functions. This paper is based on the traditional attendance system, proposed and designed a dual microstrip antenna RFID attendance system.This paper first introduces the basic principle of radio frequency identification sys-tems, its classification and data transmission coupling theory, radio frequency identification technology standards and classification systems; then describes the main function modules RFID system applications, including control modules, RF modules, interfaces modules and electronic tags section,then designed a line with international standards applied reader band microstrip antenna; in the preparation of the program, designed the control program; finally, based on the hardware platform, analysis the attendance system demand and design module and database, and ultimately complete the implementation of the system.The design in this paper achieves the dual RFID system in the attendance area, and time and attendance systems through the design, realization of innovative attendance system functionality. This well-designed traditional presence and attendance system applications are having a certain degree of innovation and good prospects.
