Abstract:

The normalized input admittance of thin bare circular loop antennas is evaluated from the theory of T. T. Wu. Computations are made for loops in air and in an infinite homogeneous isotropic dissipative medium. A comparison is also made with Storers theory of the loop. Numerical results are given in the form of graphs for several wire sizes and for loops up to 2.5 wavelengths in circumference. The properties of the medium are represented by the ratio alpha beta in the range from zero perfect dielectric to one good conductor alpha and beta are the imaginary and real parts of the complex propagation constant kbeta - j alpha omega square root of mu epsilon - j sigmaomega where mu is the permeability, epsilon the dielectric constant and sigma the conductivity of the medium.
