The impedance of an antenna probe surrounded by ionospheric plasma is examined. A review of several physical plasma parameters, research techniques, some past experimental results, and various theories is presented. A need is shown for further theoretical sophistication. The theory develops the impedance of an electrically short, cylindrical antenna probe immersed in a warm, lossy, compressible, magneto-ionic, electron fluid. The results are examined and compared to previous work and are applied to several ionospheric experiments. Experimental results as interpreted by the theory are examined and the usefulness of the theory is thus demonstrated. In particular, the theory is shown to be of value in determining electron density, temperature, and collision frequency from RF probe measurements.
