Abstract
This paper presents the design, synthesis and implementation of a chained-function in waveguide filter design for 5G implementation. A sixth-order chained-function waveguide filter centered at 28 GHz with a fractional bandwidth of 2% is validated by constructing a working simulation model in ANSYS High Frequency Structure Simulator (HFSS). The simulation model shows a good agreement with the theoretical model and the sensitivity analysis indicates that the filter draws full advantage of having high tolerance to manufacturing errors. As such, the filter can be fabricated using cost-effective additive manufacturing technology rather than the conventional Computer Numerical Control (CNC) milling system.
