Abstract
A compact design of ultra-wide band (UWB) log-periodic dipole array (LPDA) antenna printed on FR-4 substrate is presented. The proposed design consists of array of printed dipoles fed by a coaxial cable. The dimensions of the printed dipoles and the spacing between the array elements are optimized by parametric simulations using full wave simulator. The size of the fabricated LPDA antenna is 0.9 $\lambda \times 0.33 \lambda (135 \times 50 mm^{2})$. The antenna has a fractional bandwidth of 133% and covers the band from 2.2 GHz to 11 GHz. The antenna exhibits a consistent end-fire radiation patterns over the whole operating band of 2.2-11 GHz with a maximum operating gain of 8.6 dBi.
