“…A planar filter is composed of metal strips generally made of copper deposited on the upper face of an insulating substrate. These metallic strips called resonators are folded or coupled together to generate filtering functions [6]- [8]. Planar filters can be integrated with microstrip antennas and form single multifunctional devices capable of filtering and radiating which simplifies the communication chain and reduces interconnection loss [9]- [18].…”

Miniaturization in the telecommunications field is deemed a current challenge and a critical demand in order to improve communication quality between the transmitter and the receiver while avoiding clutter issues. The main objective of this work is to design a miniature interdigital bandpass filter (IBF) using planar technology. The proposed bandpass filter is made up of three equidistant parallel-coupled lines carefully deposited on a small Rogers-5880 substrate possessing a full dimension of 10×10×1.6 mm 3 , a relative permittivity 𝜀 𝑟 =2.2, and a loss tangen of 0.0009. The proposed IBF has been designed and simulated using the HFSS software, which is a simulator that studies the electromagnetic behavior of radio frequency structures using cutting-edge finite element solvers. The reached outcomes present good electrical performance in terms of insertion loss 𝑆 21 , reflection coefficient 𝑆 11 , voltage standing wave ratio (VSWR), and selectivity, making the proposed IBF suitable for integration in small electronic devices for C-band applications (4 GHz to 8 GHz).
