In this paper, a novel near-field cable-free impedance and gain measurement technique for electrically small antennas is proposed. In this technique, with the electrically small antenna placed in the near-field region of the probe, the properties of this antenna are extracted by measuring the signal scattered by it when it is loaded in turn with three known loads. The determination of the antenna...
In this paper, the relatively recently introduced double phi-step theta-scanning scheme and the probe correction technique associated with it is examined against the traditional phi-scanning scheme and the first-order probe correction. The important result of this paper is that the double phi-step theta-scanning scheme is shown to be clearly less sensitive to the probe misalignment errors compared...
