Abstract :
With the assumption that the customary current distribution and far-field distance approximations apply, this paper develops the far-field expressions for short linear antennas (2h=l<¿/10), each half immersed perpendicularly h meters in a dielectric. As an illustration of topics such as linear antennas, reflection and refraction at a dielectric interface, phasor addition of waves from several sources, etc., for the undergraduate student, the paper demonstrates that the E and H far fields at a given point in the first dielectric are invariant to the second dielectric provided the first dielectric is not changed.
