Comparative Analysis of Several Methods for Calculating the Directional Characteristics of Radiating Systems Using an Electric Dipole as an Example

The results of calculating the directional characteristics of a vertical electric dipole are presented. In the process of calculation, the method of mirror images was used, as well as an analytical expression that strictly describes the directional characteristics of a vertical electric dipole. It was revealed that the results obtained differ little from each other. It is shown that the directional properties of small-sized radiating systems can be estimated using simplified methods with a slight increase in error.
