Abstract

The present invention discloses an asymmetric broadband dipole antenna for borehole radar. The antenna comprises a substrate and a hollow metal pipe arm, the tail end of one side of the metal pipe armis arranged to be a conical body, and the interior of the metal pipe arm is divided into an upper cavity and a lower cavity through a partition plate in the length direction; the end, located on theupper cavity side, of the conical body is an open end, the end, located on the lower cavity side, of the conical body is a closed end, and the end, located on the conical body side, of the partition plate is connected with the end side wall of the conical bod. A microstrip line and a microstrip arm which communicate with each other are etched on the upper surface of the substrate, the substrate etched with the microstrip line side is placed on the partition plate, the microstrip line forms the upper conductor of an impedance converter, and the partition plate forms the lower conductor of the impedance converter; and a wire passing hole is formed in the side wall of the non-conical body end of the metal pipe arm.

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...
