Abstract

Abstract—Wideband arrays of printed dipoles with inter-element loads are investigated. A closed-form expression for the active input impedance of the array element is derived with a spectral domain approach. The proce- dure is based on an extension of the Green’s function formulation for arrays of connected dipoles to the case of dipoles coupled via loads. The accuracy of the formulation is investigated with the aid of parametric analyses. The model can be used in the preliminary design of wideband printed dipoles for the dimensioning of the radiating elements. The procedure remains ac- curate also for arrays of dipoles that are not tightly coupled, for which and the current along the element assumes a resonant-like sinusoidal distribu- tion.
