A Log Periodic Series-Fed Antennas Array Design Using A Simple Transmission Line Model

Abstract

In this paper, a transmission line model is used to design a series-fed log periodic antennas arrays over a band of frequencies for satellite communications. The transmission line model is simple, precise and allowing taking into account the whole geometrical, electrical and technological characteristics of the antennas arrays. To validate this last, the obtained simulation results are compared with those obtained by the moment’s method (MoM). Using this transmission line approach the resonant frequency, input impedance, return loss can be determined simultaneously. Agreements between transmission line model data and the moment’s methods results were achieved.
