High-frequency filters play a significant role in microwave applications, enabling effective signal processing, noise reduction, and frequency selection in communication, sensing, and electronic systems. This work proposes a 3D-printed passive structure based on inductive-capacitive passive filters for applications on the edge of the microwave range. The presented structure has a 900 mm2 area. Results show sufficient agreement between theoretical and measured cut-off frequencies in the 500-600 MHz range. Additionally, the 3D-printed structure shows an RC-like behavior, with sufficient impedance matching and an in-band minimum equal to -7 dBs. Finally, Insertion Loss equals -4 dB.

Abstract
High-frequency filters play a significant role in microwave applications, enabling effective signal processing, noise reduction, and frequency selection in communication, sensing, and electronic systems. This work proposes a 3D-printed passive structure based on inductive-capacitive passive filters for applications on the edge of the microwave range. The presented structure has a 900 mm2 area. Results show sufficient agreement between theoretical and measured cut-off frequencies in the 500-600 MHz range. Additionally, the 3D-printed structure shows an RC-like behavior, with sufficient impedance matching and an in-band minimum equal to -7 dBs. Finally, Insertion Loss equals -4 dB.Pubblicazioni consigliate
