For Antenna and RF signal traces, we usually do match circuit [1] designs separately for IT products. While, both of them are part of RF signal path and there will be deviations when we do match works separately and then put them together in one system. Hence, this paper introduces strategy to apply D.O.E. (design of experiment) [2] method for optimization of system level RF signal path with antenna design. We first design match circuits for antenna and RF signal traces separately. Then, we added variations for inductance and capacitance to cover the deviation caused by transmission lines connecting between these components. Then, D.O.E. method is applied to find optimized combinations when all things put into one system for signal path connection from RF chip to antenna.
