Frequency and Element Independent Behavior of Array Eigencurrents and its Application in Finite-Array Analysis
other
In the eigencurrent approach, the behavior of a finite antenna array is described by its ’eigenvibrations’ or eigencurrents. These eigencurrents are the eigenfunctions of the impedance operator that relates the currents on the antenna elements to their excitation fields. Eigencurrents of (large) arrays are approximated as compositions of a small number of element eigencurrents. For simple element geometries, we demonstrate that these compositions show little frequency and element dependence, and we discuss the application of this behavior in finite-array analysis.
