Abstract

We present in this work some theoretical and experimental results of utilization of loop parasitic elements in wire (dipole) and planar (patch and monopole) antennas for increasing the impedance matching bandwidth. The antennas were analyzed using our programs, based on the numerical resolution of the electric field integral equation (EFIE) by the method of moments (MoM), and using the commercial softwares IE3D and HFSS. In one of the case studied we compared numerical calculations with experimental data. The obtained results shown that the impedance matching bandwidth can be considerably enlarged with this method.
