Abstract :
A statistical characterization of an annular slot ring antenna using design of experiments (DOE) was presented. It was shown that increasing the separation between circles and decreasing the inner radius lower the impedance. Adjusting the antenna dimensions in this way also increases the resonant frequency and lowers the gain of the antenna at broadside. It was shown that the impedance of slot rings and folded slots can be decreased by increasing the slot width at the side opposite to the feed line. Future work will include a higher order model to increase the accuracy of the results and a tunable version using thin ferroelectric films
