Abstract	Introduction We discuss recent advances in antenna diagnostics from measured field data. The method proposed is based on field representation using equivalent magnetic and electric sources on arbitrary shaped geometries enclosing the antenna under test. Traditional antenna diagnostic tools are often based on a plane wave expansion similar to what is available from the corresponding planar near field measurement [1]. A more flexible approach is based Equivalent Sources (e.g. [2]), in which equivalent sources are computed on an arbitrarily shaped surface enclosing the antenna by solving the inverse problem directly from the measured field data (typically near field). Since the reconstruction surface is known, the associated inverse problem is linear; however, it is well known to be intrinsically ill-posed due to the characteristics of the operators involved. Therefore, special treatment is necessary in view of the noise present in any antenna measurements as well as to compensate for other forms of “error” in the available data (e.g. truncation). The most common such form of stabilization is the so-called regularization (e.g. [3]); it invariably results in a spatial low-pass filtering that reduces the spatial resolution, and requires the choice of a “filtering parameter” that can seldom be done a priori and in a “blind” way. To overcome these difficulties, we employ a novel and robust formulation; we will show with examples the applicability to general antenna diagnostics, leakage detection, location of antenna malfunctioning causes and identification and removal of unwanted interactions from measurements.
