On the basis of equispaced linear array synthesis, bandwidth studies of performance for different type of distributions were developed in this communication. Antenna array pattern quality parameters such as maximum Directivity, Half-Power Beamwidth, Side-Lobe Level and ripple level were evaluated.

Abstract
On the basis of equispaced linear array synthesis, bandwidth studies of performance for different type of distributions were developed in this communication. Antenna array pattern quality parameters such as maximum Directivity, Half-Power Beamwidth, Side-Lobe Level and ripple level were evaluated. Also, active impedance terms were studied: maximum absolute value, maximum real part, and absolute value of edge and central elements. To develop all these studies, embedded impedance terms -which can manage different lengths of the elements-were calculated by means of standard formulation. The key innovation of these studies is the inclusion of pure-real pattern distributions into the discussion about bandwidth performance. Accordingly, the multiplicity of equivalent pure-real and complex pattern distributions in presence and absence of ground plane have been analyzed.File | Dimensione | Formato | |
