Rancang Bangun Antena Mikrostrip Untuk Aplikasi RFID

---

In the era of digital transformation, Radio Frequency Identification (RFID) technology has become crucial for inventory management, logistics, and business automation. RFID antennas play a vital role in transmitting and receiving signals to identify objects. This research focuses on replacing traditional RFID with a custom-designed and fabricated antenna. The study begins with the initial antenna design using CST Microwave Studio, selecting an FR-4 substrate with a thickness of 1.6 mm and a dielectric constant of 4.3. Antenna characterization involves varying antenna dimensions such as ground width, slot width, and slot length to improve initial simulation results. The initial simulation results show a frequency of 2.5 GHz with a return loss of approximately -9 dB. However, after characterization, the frequency is refined to 2.4 GHz with a return loss of -22.113 dB. Despite the frequency shift between simulation and fabrication results, the accuracy analysis of the RFID antenna through testing using Arduino Uno and NRF24 demonstrates good performance. The farthest distance measurement of this antenna can reach 2 meters with obstacles, while the shortest distance is 0,5 meter with obstacles. Voltage measurements in various scenarios indicate voltage variations at longer distances. The alignment between simulation and measurement results allows for issue identification and resolution, while differences in voltage variations at longer distances can serve as a basis for further optimization in antenna design for RFID systems.
