Abstract

The invention discloses an asymmetric broadband dipole antenna for drilling radar, which comprises a base plate and a hollow metal pipe arm, the end of one side of the metal pipe arm is arranged in a cone shape, and the interior of the metal pipe arm is divided by a partition plate in the length direction Form an upper cavity and a lower cavity; the end of the cone is located on the side of the upper cavity as the opening, and the side of the lower cavity is the closed end. The end of the partition on the side of the cone is connected to the side wall of the end of the cone; the base plate The upper surface is etched with interconnected microstrip lines and microstrip arms, and the substrate on the side etched with microstrip lines is placed on the separator. The microstrip line constitutes the upper conductor of the impedance transformer, and the separator constitutes the lower conductor of the impedance transformer. Conductor; the side wall of the non-tapered body end of the metal pipe arm is provided with a wire passing hole.

Description

technical field [0001] The present invention relates to radar systems, in particular to asymmetric broadband dipole antennas for borehole radars. Background technique [0002] In view of the working system and working environment of the borehole radar system, there are high requirements on the bandwidth and size of the antenna. At present, the mainstream drilling radar system antenna is mainly based on the resistance-loaded traveling wave dipole, which can meet the bandwidth and size requirements of the system, but the radiation efficiency is relatively low, which weakens the detection capability of the radar system. Contents of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the asymmetric broadband dipole antenna for drilling radar provided by the present invention solves the problem of low radiation efficiency of the existing dipole antenna. [0004] In order to achieve the above-mentioned purpose of the invention, the technical sch...
