【摘要】 本文对对数周期偶极子天线(LPDA)的小型化形式—矩形折线振子LPDA进行了研究,提出了衡量矩形折线振子LPDA曲折度的参数,并分别对不同曲折度的矩形振子LPDA进行了研究。对不同曲折度的矩形折线振子LPDA的研究表明:矩形折线振子LPDA能有效的实现天线的小型化,提高天线的低频性能,曲折度较小时对天线的增益影响不大,较大时天线增益有所降低。更多还原

【Abstract】 In this paper, the miniaturization form of log-periodic dipole arrays antenna(LPDA)- LPDA which used rectangular meander line dipole is studied. We put forward a parameter to measure the flexuous degree of the LPDA that used rectangular meander line dipole and the different flexuous degrees of LPDA are studied. The simulation results show that using the rectangular meander line dipole for LPDA can effectively realize the antenna’s miniaturization and improve the low frequency performance of the antenna. When the flexuous degree is small, it has little influence on its gain and radiation pattern. When the flexuous degree increases, the gain will reduce.更多还原
