摘要

A frequency independent Printed Log Periodic Dipole antenna (PLPDA) with and without fractals for different materials and thickness is proposed for UWB applications.The impedance bandwidth of PLPD without fractal for FR4 of 4.71GHz to 9.99GHz.Similarly,for the RT/Duroid,the impedance bandwidth of 3.09GHz to 12.13GHz with VSWR less than two is achieved.The radiation patterns for different combinations are also observed to be an end-fire radiation pattern.In this paper,the first iteration is proposed,the parametric and performance observations are also made for different thickness (63mil,62mil,and 31mil) of the dielectric substrate.Antennas are fabricated,and its performance is authenticated using vector network analyzer (E5071C) to carry out return loss and VSWR measurements.The obtained results are insensible agreement with the theoretical results.
