基于IML工艺的天线设计方法

Research on antenna design Based on IML technique

简要介绍了一款基于IML工艺制程天线的高效设计方法。由于基于这种工艺的天线无法用传统的方法调试,所以本文采用了一种新的设计调试方法一用电磁仿真软件AMDS设计、优化天线。通过仿真找到天线的敏感区,通过设计控制、减少甚至避免在IML工艺流程中由于拉伸变形而产生的天线性能的变化。我们比对了仿真设计后生产出的IMI天线样品,得到天线的RL、效率、SAR、HAC等参数与仿真结果相符,性能达到了设计要求。基于IML天线目前业界设计的难度,采用仿真设计优化可以大量缩短设计周期,减少风险,降低成本,缩短开发时间。

In this paper,we introduced a new and high efficiency antenna design method for IML antennae.Because antenna based on this technique can not be debugged with traditional method,we used a new debug method---using electromagnetic software to design and optimize antenna.Finding antenna sensitive area in design prophase by simulation,we can reduce and even avoid antenna performance change due to tensile deformation in IML process.After producing the antenna based on IML technique,we tested their performance,found that they are in accordance with simulation and met the design requirements.For the current design difficulty of the IML antenna,simulation can shorten design cycles,reduce risk,reduce costs and shorten development time.
