Summary

Descripción general del contenido del recurso.

Abstract This paper presents an antenna loaded with metamaterial to enhance its gain and directivity to improve the performance of a ground-penetrating radar system (GPR). We adjusted the parameters of the antenna to change its equivalent capacitance and inductance and applied an operating frequency of 0.5 GHz-1.2 GHz to create an ultra-wideband antenna. On the basis of this operating frequency, we also designed the corresponding negative permittivity and permeability materials to simulate a patch antenna and material in a 1 GHz frequency band. The high gain and directivity of the antenna loaded with single-negative material were verified by simulation. Compared to the original antenna, the maximum gain increased by 7 dB and its directivity was greatly improved.
