【摘要】：提出了一种用于400MHz探地雷达系统新型蝶形天线及微带巴伦的设计。蝶形天线采用FR4单面印刷电路板制作,尺寸为300mm×150mm×2mm,其辐射臂由两级三角形贴片和一个半圆贴片组合而成。微带巴伦采用双面印刷电路板制作,通过在正反两面腐蚀出宽度线性渐变的金属带,构成双线-微带结构。实验表明:所设计的蝶形天线在310-460MHz频率范围内,回波损耗小于-10dB,其相对带宽分别是传统蝶形天线和相关文献报道的1.86和1.65倍,并具有较好的辐射特性。对于400MHz探地雷达系统,该天线及微带巴伦在性能上已达了要求,是有效可行的设计方案。
[Abstract]:A new type of butterfly antenna and microstrip Barron for 400MHz ground penetrating radar system is proposed. The butterfly antenna is made of FR4 single-sided printed circuit board. The size of the antenna is 300mm 脳 150mm 脳 2mm. The radiating arm is composed of a two-stage triangular patch and a semi-circular patch. Microstrip Barron is made of double-sided printed circuit board. By etching the metal strip with linear gradient width on both sides, the double-wire microstrip structure is formed. The experimental results show that the return loss of the designed butterfly antenna is less than -10 dB in the 310-460MHz frequency range, and its relative bandwidth is 1.86 and 1.65 times that of the traditional butterfly antenna and the related literatures, respectively, and has good radiation characteristics. For 400MHz ground penetrating radar system, the antenna and microstrip Barron have met the requirements in performance, which is an effective and feasible design scheme.
