Electrically Small Loop Antenna Loaded by a Homogeneous and Isotropic Ferrite Cylinder - Part 1
Abstract
A theoretical treatment was developed for the problem of an electrically small loop antenna loaded by an infinitely long, homogeneous, isotropoc but lossy ferrite rod. The loop which carries a constant current was idealized to be a delta-function generator. An effective magnetic current (volts) is expressed explicitly in the form of an inverse Fourier integral. The contribution to the total current from the simple pole which can be associated with the surface wave is called the transmission current while the contribution from the branch cut giving rise to the radiated field is, correspondingly, the radiation current. Also, the asymptotic behavior of the current very near the delta-function source was investigated. Two values of electrical radii of the rod are considered and for one of the cases the magnetic current is plotted for a range of values of the permeability of the ferrite rod.
