In this paper, fractal Bowtie antennas are proposed. To validate our structure and to develop an analytic method to determine the geometry parameters, the Lumped theory is used. The proposed structure is simulated using CST Microwave Studio and then Compared to the electrical Model. The proposed circuit has the same resonant aspect when comparing to the Bowtie antenna with a much reduced simulation time. The Bowtie antenna has a box with a size of 44 *80 *1.5 mm3. This antenna will be designed to an RFID Reader that resonates on 2.45 GHz.

This paper proposes a Bowtie fractal antenna designed for an RFID reader, offering several advantages over classical Bowtie antennas.The use of a simple and efficient circuit model facilitated a good analytic study.Furthermore, the simulation time was reduced, indicating a fast simulation tool.This research contributes to the development of miniaturized and efficient antennas for RFID applications.

Penelitian lebih lanjut dapat dilakukan untuk mengoptimalkan desain antena fractal Bowtie ini dengan mengeksplorasi berbagai konfigurasi fractal selain Sierpinski, seperti Koch atau Minkowski, untuk meningkatkan kinerja antena dalam hal gain dan bandwidth. Selain itu, studi tentang pengaruh material substrat yang berbeda terhadap karakteristik antena dapat memberikan wawasan untuk memilih material yang paling sesuai untuk aplikasi RFID tertentu. Terakhir, penelitian dapat difokuskan pada integrasi antena ini dengan chip RFID untuk menguji kinerja sistem secara keseluruhan dan mengidentifikasi potensi tantangan dalam implementasi praktis, termasuk studi tentang efek coupling antara antena dan chip RFID.
