The task of this tool is to achieve conjugate matching for multiple source-load impedances at an arbitrary frequencies. Maximum gain within the acceptable user-defined design parameters is achieved. Design automation feature provided by the tool relies on the built-in multi-objective optimization algorithms using Matlab software. This tool provides the designer the ability to dictate various design parameters such as source/load complex impedances, frequencies of operation, bandwidths, and VSWR to be achieved simultaneously. Starting with suggesting applicable circuit configurations, the proposed CAD tool provides the acceptable operating ranges for each component, and the corresponding design parameters. The included interactive feature gives the designer extra degree of freedom to study the impact of each component on the whole network performance. To demonstrate the interesting features of the proposed CAD tool, a wide-band antenna is introduced as a practical case study to be matched with 50-$\Omega$ load. Based on the predefined constraints, the tool provides many solutions to solve the matching problem with the user constraints.
