Abstract

An ultra-wideband low cross-polarization printed log-periodic dipole antenna (LPDA) is systematically investigated. The properties of the proposed antenna have been Simulated and optimized with electromagnetic simulation software FEKO 6.2. The antenna possess the operating bandwidth from 0.8GHz to 7.2GHz with the return loss less than -10dB, the cross-polarization and side lobe level are less than -30dB. The Gain of the antenna is greater than 8.25 dB during the operation bandwidth, and very good End-fire directivity is obtained.
