摘要:

传统偶极子天线结构存在偶极子臂细、安全性低、天线走线占用空间大、增益特性差等问题,提出多应用环境下螺旋形印刷微带偶极子天线设计与优化方法。初始化微带偶极子天线工作结构,设计加粗偶极子臂的螺旋形印刷天线,减小天线走线占用空间。设计振子方向、振子阻抗特性,推导出最优结构参数。实验证明可知,在330MHZ-332MHZ的有效范围内,驻波比小于1.30dB ,在331.5MHZ-334.9MHZ有效范围内,回波损耗小于-10dB,其方向对称性较好,天线输入端驻波比与回波损耗较为理想,该天线具有较好特性。

Abstract:

The problem is fine, the dipole arm low safety, antenna wiring space and gain characteristics of difference existing in the traditional dipole antenna structure, the multi application environment of spiral printed microstrip dipole antenna design and optimization method. The work structure of microstrip dipole antenna is initialized, and the spiral printed antenna with bold dipole arm is designed to reduce the occupied space of antenna line. Design the oscillator direction and the impedance characteristics of the oscillator, and derive the optimum structural parameters. Experiments show that the effective range in time, in less than Bobbi, within the effective range, the return loss is less than its direction, good symmetry, the antenna input in Bobbi and the return loss is more ideal, this antenna has good characteristics.
