This paper describes the practical application of the inverse-source or source-reconstruction technique as a detailed antenna diagnostic tool [1-5]. The investigated antenna is intended as part of the European Navigation System GALILEO and is a pre-development model flying on the InOrbit Validation Element, GIOVE-B satellite. The array antenna, developed by EADS-CASA Espacio, consists of 42 patch...
The equivalent radiating current technique (EQC) is based on an integral equation formulation of the inverse source problem upon rigorous application of the equivalence principle [1]-[8]. From the measured near or far field data it allows the accurate determination of the equivalent radiating sources on an arbitrary 3-D closed surface enclosing the Antenna Under Test (AUT). The main advantage of the...
The inverse source or equivalent current/source method (EQC), [1]–[7], based on discretization of integral equations has attracted considerable attention due to a host of promising applications in antenna design and diagnostics. This method offers a greater generality and flexibility since it allows reconstructing sources on arbitrary 3-D surfaces enclosing the antenna under test (AUT). Indeed the...
