Abstract

In this article we discuss in detail the numerical implementation and computer simulations based on the Method of Moments (MoM) of the reconfigurable, ultra wideband (UWB) log-periodic antenna. The manufacturing and testing procedures are also addressed. The antenna was built utilizing low cost and/or recyclable materials and covers frequencies from 74 MHz to 2 GHz, through the discrete adjustment of its elements. The gain in a given frequency band of operation can also be changed by the reconfiguration of its elements. This antenna can be widely used in developing countries where scarce resources limit both the use of antennas in educational laboratory experiments and their use in industrial applications.
