Abstract
In this work, antenna is studied as an important part of Ground Penetration Radar (GPR). For obtaining information about materials in two different depths, a novel double band bow tie antenna is proposed. Fractal method is used for improving theantenna performance. The results of the antenna development is presented step by step. The low cost and light profile designed antenna has been fabricated and tested in microwave laboratory. The fabricated antenna results agree well with the simulation analysis.
