A novel setup, based on the use of non-invasive dielectric field probes, and employing accurate and reliable algorithms for antenna characterization, is described. Experimental results show how the proposed system can provide even more accurate characterizations than standard near-field systems, enabling considerable reduction of indoor test-range dimensions (compact near-field). Also, the potential for very-near-field acquisition, as well as the sampling strategy in the reactive zone of the radiator, are pointed out.
