ABSTRACT:
An antenna arrangement for use in a bore hole to receive radar signals and produce electrical signals from which the incidence direction of the radar signals can be determined includes a cross coil arrangement with two coils having elongated sides mounted adjacent the outer surface of a cylindrical insulative probe body. In one embodiment, one cross coil assembly is used in conjunction with an omnidirectional antenna and an evaluation circuit. In another embodiment two axially aligned cross coil assemblies are connected to also be usable as an omnidirectional antenna.
