Polar Tuned Dipole Installation:
I added a few new photos today, Thursday the 12th, 2014.
Thanks to ken and bob for the images.
Polar Tuned Dipole
Employing Electromagnetic Theory is key.
Starting with the theoretical impedance of a half wave dipole
antenna of 73 + j 42.5. One must understand, with any physical load, the antenna has a complex impedance. The resistive part accounts for heat losses in the antenna, in the radiated energy and losses in the medium surrounding the antenna. Since there will be an electromagnetic field near the antenna parts then there will be energy stored in the field(s). This stored energy gives rise to the imaginary part of the effective antenna impedance. Analysis began with electrostatic and magnetostatic fields; Laplace’s and Poisson’s equations; Boundary value problems and their solutions; Maxwell’s equations; application to wave propagation in bounded and unbounded media; Transmission lines : basic theory, standing waves, matching applications, microstrip lines; Basics of wave guides and resonators; Elements of antenna theory all were used in the development of the Polar Tuned Dipole.
