Abstract:
The purpose of this thesis is to design and test a device that measures the electrical parameter sofa certain material. This device can have different applications, like assisting in land mines detection, agricultural or construction purposes. In order to measure the electrical parameters, this device or probe uses two wideband planar dipole antennas that operate in the frequency range between 3 and 6 GHz. The transmitted signal between the antennas, (S21), is measured and then compared to a database obtained by simulating different materials using the Finite Difference Time Domain Method. Based on this comparison, one can extract the dielectric constant and conductivity of the material. Preliminary results show that this probe can be used with reasonable accuracy to measure in-situ the electrical parameters of soil.
