摘　　要：发明问题解决的理论(teoriya resheniya izobreatatelskikh zadatch,TRIZ)作为一种理论工具和创新的现代技术,是一种科学创新方法,它提供了一套完整的创新工具,从不同角度分析问题并寻找的解决方案。本论文将TRIZ创新方法和天线设计相结合,通过运用TRIZ中最佳理想解定义和系统功能分析两种方法,导出天线设计中关键的需要优化参量;以此作为设计的出发点,基于高频天线结构仿真(high frequence structure simulator,HFSS)平台设计出一款工作于5.8 GHz的嵌入式微带单元天线阵列,经过仿真、实物制作、测试和优化,回波损耗(S11)达到-15 dB以下,并且具有较好的方向性及较窄的带宽。本论文为TRIZ运用于专业实践设计提供了一定的方法参考。As a theoretical tool and modern innovation technology,teoriya resheniya izobreatatatelskikh zadatch(TRIZ)has been a powerful methodology for innovation in science, providing a complete set of tools to analyze and find out solution scheme from different perspective. Combining TRIZ and antenna designing, this paper introduces how to apply ieal final resolution(IFR) and system functionality analysis to derive some key parameters to be optimized;based on the results via TRIZ analysis, an embedded micro-strip antenna array with 5.8 GHz resonant frequency is designed by means of high frequence structure simulator(HFSS) simulation platform. Through simulating, making hardware, testing and optimizing, the S11 of the array can be down to-15 dB and has good directivity and narrow band. This paper presents how to apply TRIZ to speciality field, which indicates an innovation methodology reference.
