Abstract
In this paper, a small microwave bandpass filter operating at 3.5 GHz is designed and simulated for use in fifth-generation (5G) applications. The proposed filter is suitable for textile integration as it offers reduced size, low insertion loss and im-proved frequency selectivity by combining zigzag transmission lines with stepped impedance resonators (SIRs). CST Microwave Studio was used to simulate on a felt textile substrate. The flexible design is compatible with portable systems, fa-cilitating the constant mobility of the human body while maintaining constant electromagnetic performance. Thanks to these features, the proposed filter is an excellent option for wearable 5G systems, such as body sensor networks, Inter-net of Things applications and smart e-health wearables.
