A Design For the Shortwave Antenna on the Electromagnetic Wave Model

摘要

According to multi-ionosphere models, this passage analyzes the influence of the ionosphere on the propagation of the electric wave, so does the relations between the frequency and radial elevation range, based on which take the short-wave horizontal bipolar antenna for example to design and execute numerical simulation. Considering the impact of the environment, the synthesis method of MOM and FDTD is explored. These provide technical guidance for choosing the antenna type, the location place, and the erection, debugging of the antenna.
