The dipole antenna is a half-wavelength structure made of wire, tubing, printed-circuit board (PCB) copper, or some other conductive material. It is divided into two equal quarter wavelengths and ...

1. The electromagnetic field around a half wave dipole consists of an electric (E) field (a) and a magnetic (H) field (b). The fields are spherical and cut across one another at right angles.

Formulae are derived for calculating the field strength distribution for the types of broadside array normally used for short wave broadcasting, namely arrays consisting of rows of colinear half ...
