摘要

探地雷达(GPR)的天线设计非常复杂，取决于具体的应用。在典型的土木工程探地雷达应用中，天线需要成本低、体积小、结构紧凑、结构简单，同时在近地、宽频带范围内工作。本文提出了一种超宽带抛物面双锥天线。除了结构紧凑和体积小之外，双锥天线的设计参数和给出的程序可以用于特定的探地雷达应用。该天线在0.67 ~ 4.3 GHz的超宽带范围内实现VSWR > 2，总高度为11.8 cm。该天线的时域响应在最大辐射方向上的激励信号失真可以忽略不计。此外，在土木工程探地雷达应用中，当天线非常接近典型的实际地面时，可以获得很好的驻波比。

Ultra-wideband parabolic bicone antenna for ground penetrating radar

Antenna design for ground penetrating radar (GPR) is very complex and depends on specific application. In typical civil engineering GPR applications, the antennas need to be low cost, small size, compact and simple while operating in close vicinity to real ground and in wide frequency band. In this paper we propose an ultra-wideband parabolic bicone antenna. Except for its compactness and small size, the bicone antenna design parameters and the given procedure can be used for a specific GPR application. The proposed antenna achieves VSWR > 2 in ultra-wideband from 0.67 - 4.3 GHz with the total height of 11.8 cm. Time domain response of the proposed antenna shows a negligible excitation signal distortion in the direction of maximum radiation. Also, very good VSWR is obtained when the antenna is very close to the typical real ground found in civil engineering GPR applications.
