HF Satellite Antenna Analysis,

Abstract

Results of a satellite antenna analysis using the Antenna Modelling Program (AMP) are presented. A satellite structure with an HF dipole antenna attached was simulated using a wire grid model. The HF dipole antenna is part of a receiving system in earth orbit used for an ionospheric ducted mode experiment. The antenna gain patterns for several possible satellite antenna configurations are presented and analyzed to determine acceptable configurations for the ducted mode experiment. Examined were the influence of dipole element length, orientation of the elements, and their positioning with respect to the satellite structure for frequencies from 6 to 30 MHz. Also, the antenna impedances were calculated to determine the possible losses when the antenna is terminated in a resistive impedance load. The influence of the ionospheric plasma on the mismatch losses was also estimated. (Author)
