<p>In this study, a novel and systematic methodology
for the design and optimization of conductor-backed coplanar waveguide (CB-CPW)
based low pass filter (LPF) is proposed. The width of the signal trace is
continuously varied using a truncated Fourier series, and the adjacent gaps are
designed in several types established on a specific optimization setup to
obtain predefined electrical characteristics with maximum compactness taking
into account physical constraints. Trust-region-reflective algorithm (TRRA),
genetic algorithm (GA), and particle swarm optimization algorithm (PSO) are taken
into account to minimize the developed bound-constrained non-linear objective
function respectively.<br></p><p>All types are programmed and analytically
verified in MATLAB. Solutions include design parameters such as the physical
length and width of the structure, which will be drawn in AutoCAD later on.
Also, the optimized layouts are exported to Ansys High Frequency Structure
Simulation (HFSS) software for simulation and validation. Non-uniform CB-CPW
LPFs are optimized and simulated over a frequency range of 0-6 GHz with a
cutoff frequency of 2 GHz. Simulation results show a good agreement with the
analytical ones.<br></p>
