为了提高SMA同轴微带连接器的电性能指标，提出一种新设计的SMA同轴微带连接器。该连接器采用2个绝缘支撑限位固定内导体和外导体的相对位置。连接器的尾部采用外导体零件进行压接装配，保证了连接器的机械可靠性；外导体和绝缘支撑没有开孔灌注环氧树脂胶，从根本上规避了连接器的电磁泄漏隐患；并通过仿真优化，整个连接器具有较小的电压驻波比以及较低的插入损耗。采用共面补偿测试方法，所设计的连接器在工作频率范围内，测试电压驻波比VSWR＜1.13，插入损耗＜0.15 dB，电磁泄漏＜-90 dB，较现有的SMA型同轴微带连接器的性能指标都有明显改善。

Presents a new design of SMA coaxial micro-strip connector in order to improve the SMA coaxial micro-strip connector electric performance index. Two insulated mediums are adopted to fix the relative location of the inner conductor and outer conductor of the proposed connector. A part is pressed into the end of the proposed connector as a part of the out conductor so as to ensure the dependability of the designed connector. The structure of no holes in the outer conductor and the insulated mediums is adopted to avoid the problem of electromagnetic leakage. The proposed connector has good performance of low VSWR and low inserting loss by optimization design. By adopting the improved measurement method of coplanar-offset, the proposed SMA-type coaxial micro-strip connector has good performance, VSWR<1.13, inserting loss<0.15 dB, electromagnetic leakage<-90 dB, which are all better than the performance of current connector.
