Abstract :
Yagi antennas operating at 25 MHz over real ground have been modelled at microwave frequencies. The method of modelling ground, the measurement of its electrical parameters and the apparatus for measuring radiation patterns of model antennas are described. Typical radiation patterns obtained are compared with those predicted from theory.
