摘要

研究了一种新的GPS微贴片天线设计。设计并仿真了在L1频段(1575 MHz)周围工作的70个天线迭代,并在贴片上设计了不同尺寸的四分之一圆槽。同时,将“设计尺寸参数(“r”槽半径和“h”衬底厚度)和参数对应的天线谐振频率”应用到曲线拟合算法中,得到了基于r和h的谐振频率方程,并与仿真结果进行了比较。

A new design micropatch antenna for GPS applications on vehicle navigation systems
A new design of the micropatch antenna for GPS applications is studied. 70 antenna iterations working around the L1 band (1575 MHz) with different sized quarter-circular slots on the patch are designed and simulated. In parallel, “design dimensional parameters (“r” slot radius and “h” substrate thickness) and antenna resonant frequencies according to parameters” are applied to curve fitting algorithm and an equation for resonance frequency is obtained based on r and h. The resonance frequency values obtained by proposed equation are compared with simulations.
