Analysis of a UHF Log-periodic Antenna

Abstract

This investigation uses the method of moments (MoM) approach to model a 2:1 bandwidth UHF log-periodic antenna (LPA) with the emphasis on designing the best possible front-to-back (F/B) ratio, rather than maximum forward gain. The use of non-resonant parasitic elements embedded in the log periodic structure was investigated to determine its effect on broadband matching and the F/B ratio.
