Abstract :
The dielectric wedge antenna is studied here as a wideband antenna that is can be sensitive to signals propagating along or just out of a dielectric surface. This is of particular interest in using GPR techniques to identify the condition of a road and may well find broader applications. Measured and theoretical results agree well and show the wideband characteristics that are sought. The antenna exhibits some tolerance to the dielectric properties of the ground being illuminated. The cross polarisation properties of the antenna are naturally compromised when monitoring media in the immediate vicinity of the antenna, but are quite good.
