Equivalent circuit modeling of UWB antennas for system co-design

A new wideband physical augmentation based modeling technique has been presented. In this method, all series augmentation elements are transformed into the parallel ones. Using this technique, the preliminary analysis of the circuit to decide the augmentation type is not needed. The type of augmentation to be performed can be determined automatically. The proposed methodology has been employed to extract the equivalent circuit for a UWB antenna. The results show good correlation with the EM data.
