Reduced size planar Log-Periodic Dipole Arrays (LPDAs) using rectangular meander line elements

Abstract

Two different designs for planar LPDAs were designed and measured. Both designs showed low return loss and high F/B ratio, accompanied by an acceptable value of gain. A comparison between them showed that the meander design has similar properties to the Euclidean design, while it occupies less space in the antenna system and thus less weight.
