“…Subsequently, the two-port S-parameters can be determined by the method presented by Aberle in [34]. • if the radiation efficiency of an electrically small antenna is unknown and it radiates spherical waves, two-port Sparameters can be determined by SWC method presented by Thal in [38] and [39], [40].…”

“…This section presents the measurements, calculations, and simulation results, which are used to validate the proposed model. Since all antennas used in the verification are electrically small single-mode monopole antennas, whose Sparameters are measured using methods in [38]- [40], the applicability of this method to other types of antennas has not been confirmed. Four different monopole arrays are tested to validate the model.…”

An antenna can be modeled as a two-port network using S-parameters. However, having individual antenna Sparameters is not sufficient for modeling an array of antennas as antennas exhibit mutual coupling. This article proposes a network model to represent an antenna array with mutual coupling. Using the proposed model, an N-element antenna array is modeled as a combination of two-port networks representing each element and an N-port network representing mutual coupling. Two techniques to calculate mutual coupling S-parameters are presented: a primary method using numerical solutions and an approximate method using approximate expressions. The proposed model was validated using four monopole arrays having different interelement spacings, the number of elements, and non-identical antennas.
