Abstract :
The use of a two element dipole array for near vertical incidence skywave (NVIS) communications is computationally investigated. The antenna is placed close to the vehicle of interest, namely the Assault Amphibious Vehicle (AAV), and the effect of different grounds on the input impedance, efficiency, Q-factor, and BW of the antenna and vehicle system are determined. Good corroboration of the conducted method of moments analysis with finite element method is obtained, thus validating this work´s conclusions.
