Abstract

A method to reduce the size of a conventional LPDA is discussed. T-top loaded dipoles are implemented in the array instead of λ/2 dipole elements to achieve a reduced size and maintain co-planar geometry. Each dipole in the array is reduced in size by 50 % (kr = 0.8). The simulated S11 of the size-reduced LPDA is maintained below -10 dB across the conventional LPDA's bandwidth from 35 MHz to 60 MHz. The size-reduced LPDA has directive realized gain reaching 9.5 dBi.
