In the rapidly evolving world of wireless communications, keeping pace with the demands of IoT and Industry 4.0 requires innovative solutions. Enter metamaterial filters a groundbreaking technology that’s reshaping the landscape of wireless communication. In this article, we present the creation of an innovative structure of a metamaterial Dual bandpass filter for various applications. The suggested filter consists of two cells of metamaterial units that have a symmetrical shape. Through the use of these two cells, it offers improved filter performance. The simulation, carried out with HFSS software, reveals that the developed filter has very good passing performance, with an insertion loss of 0.1 dB for the first bandwidth, 0.18 dB in the second band width, and a return loss of more than 31 dB on all frequency bands. Its central frequencies are 1.9 GHz and 3.3 GHz. In addition, the filter has a very small size of 18.46 × 13.5 mm2. The simulated results indicate that the suggested metamaterial filter is suitable for multi-band wireless applications such as GPS (1.9 GHz), and Wi-MAX (3.5 GHz) and WLAN (3.4 GHz).

摘要

In the rapidly evolving world of wireless communications, keeping pace with the demands of IoT and Industry 4.0 requires innovative solutions. Enter metamaterial filters a groundbreaking technology that’s reshaping the landscape of wireless communication. In this article, we present the creation of an innovative structure of a metamaterial Dual bandpass filter for various applications. The suggested filter consists of two cells of metamaterial units that have a symmetrical shape. Through the use of these two cells, it offers improved filter performance. The simulation, carried out with HFSS software, reveals that the developed filter has very good passing performance, with an insertion loss of 0.1 dB for the first bandwidth, 0.18 dB in the second band width, and a return loss of more than 31 dB on all frequency bands. Its central frequencies are 1.9 GHz and 3.3 GHz. In addition, the filter has a very small size of 18.46 × 13.5 mm2. The simulated results indicate that the suggested metamaterial filter is suitable for multi-band wireless applications such as GPS (1.9 GHz), and Wi-MAX (3.5 GHz) and WLAN (3.4 GHz).
