Perancangan dan Analisis Antena Mikrostrip Meander Line untuk Aplikasi RFID Reader (915 Mhz)

Abstract

RFID (Radio Frequency Identification) has become an important technology in many applications, such as inventory management, process automation, and pass-through management. In this study, a meander line microstrip antenna will be designed which is expected to have good performance at a frequency of 915 MHz. Design method using CST 2019 application simulation. Various antenna parameters, such as antenna dimensions, line width, distance between lines, and ground plane are optimized to achieve desired performance characteristics. The simulation results in the initial design showed the return loss value is -6.096 dB, and the VSWR value is 2,965. Then, the simulation results after optimization of the meander line microstrip antenna at a frequency of 915 MHz resulted in a return loss value of -29,317 dB, and a VSWR value of 1,071
