Analysis of the logperiodic Vdipole antenna
Abstract
The logperiodic Vdipole antenna (LPVA) operating in the 3 lambda/2 mode is analyzed numerically using the projective technique. The antenna is treated as a parallel connection of an array of Vdipoles and a feeder transmission line. This decoupling of the circuits enables one to obtain the dipole currents simply by considering the array of Vdipoles as a boundary value problem and solving the necessary integral equations. The currents can then be used to give the various properties of the antenna. Effects on the antenna behavior obtained by changing its parameters are illustrated, and general characteristic curves presented.
