Description

Technical Field

[0001] The utility model relates to the technical field of ground penetrating radars, in particular to a miniaturized ultra-wideband ground penetrating radar antenna. Background Art

[0002] Electromagnetic waves are emitted to the ground through the transmitting antenna. When the electromagnetic waves reach the underground target or the interface between different media, they are reflected. The receiving antenna captures the reflected wave information carrying the target characteristics, such as the intensity, phase, delay and waveform of the reflected wave. By processing this information, ground penetrating radar images can be produced to reflect the specific information of the underground structure and target.

[0003] Common ground penetrating radar antenna forms include butterfly antenna, helical antenna, tapered slot antenna and TEM horn antenna, but these technical means still have some shortcomings. For example, as a non-frequency-variable antenna, the spiral antenna has the advantages of wide bandwidth and stable radiation pattern, but the time domain ringing effect is significant and it is not suitable for pulse radar. The tapered slot antenna and TEM horn antenna have the advantages of wide bandwidth and high gain, such as Vivaldi antenna, but the size is large and it is difficult to meet the requirements of low profile of ground penetrating radar. At the same time, the tapered slot antenna is also easily interfered by the environment due to its open structure. Although the butterfly antenna has the advantages of wide bandwidth, compact structure and convenient processing, it has the disadvantages of large variation in radiation pattern and significant deterioration of the antenna's front gain in the local frequency range after loading the shielded back cavity. The butterfly antenna with a reflective back cavity improves the backward radiation and improves the isolation between the transmitting and receiving antennas by improving the shape of the butterfly antenna and adding absorbing materials.

[0004] The above device has the following defects, but the size of the antenna is large, and the antenna is not further miniaturized, which affects the portability of the user. Therefore, a miniaturized ultra-wideband ground penetrating radar antenna is proposed to solve the above problems. Utility Model Content

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a slide groove, which is opened on the top inner wall of the butterfly-shaped antenna plate, one side of the inner wall of the slide groove is slidably connected with an adjustment plate, one side of the outer wall of the adjustment plate is fixedly connected with an arc block, and the outer wall of the adjustment plate away from the arc block is fixedly connected with a spring.

[0008] As a further description of the above technical solution: a wear-resistant pad is fixedly connected to the inner wall of the side of the slot.

[0010] As a further description of the above technical solution: the thickness of the graphene plate is two millimeters, and the thickness of the copper plate is three millimeters.

[0011] As a further description of the above technical solution: the arc block passes through one side outer wall of the butterfly-shaped antenna plate, and the arc block is clamped on both side inner walls of the clamping slot.

At the same time, the material of the heat dissipation hole is improved and the heat inside the ground penetrating radar body is discharged and dissipated through the through hole, so as to improve the long-term signal reception and the stability of the transmission bandwidth.
