【摘要】:提出了一種用于400MHz探地雷達(dá)系統(tǒng)新型蝶形天線及微帶巴倫的設(shè)計。蝶形天線采用FR4單面印刷電路板制作,尺寸為300mm×150mm×2mm,其輻射臂由兩級三角形貼片和一個半圓貼片組合而成。微帶巴倫采用雙面印刷電路板制作,通過在正反兩面腐蝕出寬度線性漸變的金屬帶,構(gòu)成雙線-微帶結(jié)構(gòu)。實驗表明:所設(shè)計的蝶形天線在310-460MHz頻率范圍內(nèi),回波損耗小于-10dB,其相對帶寬分別是傳統(tǒng)蝶形天線和相關(guān)文獻報道的1.86和1.65倍,并具有較好的輻射特性。對于400MHz探地雷達(dá)系統(tǒng),該天線及微帶巴倫在性能上已達(dá)了要求,是有效可行的設(shè)計方案。
[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.
