Abstract :
This paper distinguishes between the active and passive states of an array element and advances the thesis that models defined in the passive state maintain their validity in the active state. The influence of reactance at the base of an array element is demonstrated and analytical expressions are suggested to aid in quantifying the base reactance. A model architecture is proposed together with methods for determining the model parameters. Examples of both analysis and design are included and the results are compared to measured data
