Abstract

The invention relates to a bow-tie antenna device, in particular to an ultra-wideband cavity-backed bow-tie antenna device for a ground penetrating radar, and aims to solve the problems that in the prior art, a cavity-backed bow-tie antenna with the 3dB bandwidth ranging from 50 MHz to 300 MHz and a cavity-backed bow-tie antenna with the 3dB bandwidth ranging from 300 MHz to1 GHz cannot share one type of trailers, walking measurement with the height of an antenna radiating surface away from the ground cannot be achieved in an adjustable mode, and grounding measurement of the antenna radiating surface cannot be achieved. The device comprises a cavity-backed bow-tie antenna, a first common trailer with landing controllable, a second common trailer with landing controllable and a common frame, wherein the first common trailer with landing controllable is installed on one side of the common frame, the second common trailer with landing controllable is arranged on the other side, opposite to the first common trailer with landing controllable, of the common frame, and the cavity-backed bow-tie antenna is fixedly installed on the common frame through threaded connection. The ultra-wideband cavity-backed bow-tie antenna device belongs to the field of earth probing.

Description

technical field [0001] The invention relates to a bow-tie antenna device, in particular to a ground-penetrating radar ultra-wideband cavity-backed bow-tie antenna device, which belongs to the technical field of earth detection. Background technique [0002] In order to transmit and receive radar signals with ultra-wideband spectrum efficiently and without distortion, the receiving and transmitting antennas of the ground penetrating radar system must have good ultra-wideband performance. Distributed loading cavity-backed bowtie antennas can suppress unnecessary radiation fields, and at the same time reduce the influence of the surrounding environment and metal parts and electronic components in the system on the antenna radiation performance, so the shielded cavity-backed bowtie antennas whose inner walls are covered with absorbing materials Be the first choice. Normally, according to the triangular bow tie antenna theory, the 3dB bandwidth is about 50MHz~300MHz when the cen...
