Oil field radar logging antenna

The utility model relates to an oil field radar logging antenna, which comprises a dipole antenna of a loading resistor, a ferrite and a metal baffle plate, wherein the ferrite is fixed on one side of the dipole antenna; and the metal baffle plate is fixed on the back face of the ferrite. When radar logging is required to be performed, an electromagnetic wave is reflected by the metal baffle plate, so that main energy is radiated to one side of the dipole antenna, and residual energy is converted into energy existing in other forms and consumed away in the ferrite; and therefore, an aim of orientation is fulfilled, a ratio of the main peak of a waveform of a received signal to the main peak of a waveform of a tailing signal is more than 10 to 1, and an amplitude ratio of a forward waveform to a backward waveform is more than 3 to 1. After the signals are processed, positions of media, such as petroleum, water and the like, can be determined accurately.
