Transverse current on strip dipole antenna
Abstract
Analyses of the current of thin wire dipole antennas presuppose that the current is parallel to the antenna axis. It is pointed out that a component of current transverse to the antenna axis can exist for antennas having a noncircular cross section, such as the strip dipole. The present investigation is concerned with a perfectly conducting strip antenna which is center driven by a delta function generator, taking into account the surface currentdensity components Kx(x,z) and Kz(x,z). In the solution of the resulting integral equations, it is assumed that Kz is considerably stronger than the transverse surface current density Kx. After obtaining an approximation to Kz, the second integral equation is solved for Kx. Results for the normalized transverse surface current density are presented in graphs.
