Abstract:

A proposed probe for measuring the parameters of the ionosphere is described. The probe system consists of an energized spherical slot antenna, with three sets of auxiliary slots, disposed around the sphere in orthogonal orientations to the energized slot. Results of a complete mathematical analysis of an ionosphere probe system are given. Specifications and requirements for a typical ionosphere probe are discussed. This includes recommendations for sphere size, slot lengths, cavity feeds, and the admittance measurement system. The auxiliary slots can also be used for the telemetr antennas. Author
