Abstract

This paper presents a wide-band Yagi-Uda antenna with X-shape driven dipoles and parasitic elements using differential evolution algorithm (DE). In the optimization process, a method of moments code, NEC code simulates the antenna designs generated by DE. In order to illustrate the capabilities of the method, a nine-element Yagi-Uda antenna is given. The measured and simulated impedance bandwidth of VSWR<;1.8 reaches 19.0%, which is three times the bandwidth of the Yagi-Uda antenna using a dipole driven element. The maximum gain over the operating frequency band is 12.7dB. The results are compared with Nelar Mead method in an equally spaced array design.
