An Exact Solution of Electromagnetic Field in Far Zone Radiated by Contra Wound Toroidal Helical Antenna

摘要

In this paper, a Contra Wound Toroidal Helical Antenna (CWTHA) having elliptical toroid core is realized. The realization is based on mathematical computation of exact solution of the vector potential. The nature of the current flowing through CWTHA is assumed to be constant. In connection with the geometry of CWTHA, elliptical toroid core is chosen having major axis a, minor axis b with turn radius r and solution of vector potential is generalized with N number of turns.
