Abstract

The invention relates to the design field of amphibious ground-penetrating radar antennas, in particular to an ultra-wideband elliptical planar dipole antenna. In the present invention, slots are made on the antenna sheet of the elliptical planar dipole antenna, and resistance is loaded on the slotted slits, so as to realize the characteristics of miniaturization, ultra-wideband and excellent time-domain performance of the elliptical planar dipole antenna . At the same time, the watertight shell is used to ensure the watertight characteristics of the antenna, and finally the elliptical planar dipole antenna can adapt to the amphibious work requirements, realizing its miniaturization, wide working frequency band and excellent time domain performance. The operating frequency ranges of the antenna in the invention are 30MHz-50MHz and 170MHz-270MHz respectively in two environments of water and air, and the time domain performance is excellent.

Description

technical field [0001] The invention relates to the design field of amphibious ground-penetrating radar antennas, in particular to an ultra-wideband elliptical planar dipole antenna. Background technique [0002] Ground-penetrating radar has the advantages of work efficiency, high detection accuracy and non-destructive detection. It is currently mainly used for the detection of land minerals and underground structures. [0003] my country has a large number of lakes, reservoirs and rivers. The exploration of underwater topography is indispensable for engineering construction. Only by knowing the underwater geography can we design targeted dams and bridges. For underwater cultural relics buried in rivers and lakes , The archaeological excavation of urban ruins is also inseparable from underwater exploration. At present, underwater exploration mainly uses methods such as human diving, magnetotelluric method, and high-density electrical method. These methods have made great con...
