dc.description.abstractAn experimental technique is presented to determine the aperture reactance of a short, radio frequency (RF) coaxial probe. The method is based on the inversion of the measured reflection coefficient at the probe's input port. The work was done at 500 MHz using an HP8510C network analyzer and high quality calibration standards. For precise inversion the attenuation and phase constants of the coaxial line must be determined with high accuracy. To a good approximation the measured probe capacitance was found to increase linearly with length from the value for a flush probe. This allows the CW capacitance of a short probe, with length up to 1/10 free-space wavelength, to be modeled using a simple two-term model. Bare and insulated probes, both shielded and unshielded, were studied.
