Abstract :
We propose a new completely variable reconfigurable antenna for Ground Penetrating Radar (GPR) applications. In particular, here we present the design and the numerical analysis of the structure in total geometry morphing approach, with the aim of simulating the specific behavior of a reference bow-tie dipole. The development environment of the new device was the numerical tool HFSS (High Frequency Structure Simulator) by Ansoft which exploits the Finite Element Method (FEM). Finally, we extend the analysis of a single antenna by investigating the effect of a receiving one on the radiation properties of the transmitting antenna in dependence on the distance between them.
