Resistance Loaded TEM Antenna For Ground Penetrating Radar

Subsurface radar, also known as ground-penetrating radar is increasingly being used for the detection and location of buried objects such as mines and structures that are found within the upper regions of the earth's surface. The thesis gives a review of the work done to date in this area, laying emphasis on the possible antenna designs to match the range of intended applications. An overall design strategy is outlined, together with a more detailed treatment of the ground-penetrating radar subsystems and topics which are relevant to effective subsurface radar operation. These include the dielectric properties of earth materials, the choice of the frequency of operation, as well as the design and construction of suitable antennas. Finally, A TEM antenna was simulated. The coupling of two antennas and the tail of the reflected signal of the antenna are reduced. Furthermore, the antenna was tested with the GPR...
