Abstract

The invention relates to the design field of an amphibious ground penetrating radar antenna, in particular to an ultra-wideband elliptical planar dipole antenna. The invention realizes the miniaturization of the elliptical planar dipole antenna, the ultra-wideband and the excellent performance in the time domain by slotting the antenna chip of the elliptical planar dipole antenna and loading a resistor on the slotted slot. At the same time, the watertight shell is used to ensure the watertight characteristics of the antenna, so that the elliptical planar dipole antenna can adapt to the workingrequirements of the amphibious and terrestrial, and realize its miniaturization, wide operating frequency band and excellent performance in time domain. 30 MHz to 50 MHz and 170 MHz to 270 MHz in watand air environments, respectively, and that antenna has excellent time domain performance. The antenna has the advantage that the frequency range of the antenna is 30 MHz to 50 MHz and 170 MHz to 270 MHz in water and air environments, respectively.

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...
