Abstract

Rigorous equivalent circuits representing the unit cell of
a connected array in transmission and reception are
derived in this paper. These equivalent networks are not
based on reciprocity but on Green¿s functions. Thus, all
components have well identified and physically
meaningful roles. A dual-band connected array
demonstrator is then presented to validate the theory.
The matching properties of the array are characterized
via Radar Cross Section (RCS) measurements without
resorting to lossy and expensive feeding networks.
