摘要

摘要:
由于传统TEM小室的频带宽度不能满足日益增长的宽频带需求，该文采用同轴结构设计了一个DC-6 GHz的宽带电磁辐照装置。该装置基于传输线理论和阻抗匹配原理，采用锥形过渡与圆同轴连接的结构，在端口处选用N型连接器，与腔体的连接实现了良好的阻抗匹配。利用CST仿真软件进行建模优化，最后对仿真结构进行加工与调试，仿真结果表明，该同轴电磁辐照装置在DC-6 GHz频率范围内S11均在–10 dB以下，由于加工的误差测试结果在个别频点稍有偏差，但趋势和仿真结果具有较好的一致性，吻合较好，证明该辐照装置具有良好的传输性能。该文设计的同轴腔在电磁辐照系统中具有很好的应用价值。

Abstract:
As the bandwidth of the traditional TEM cell can not satisfy the growing demand for broadband, a broadband electromagnetic radiation device working from DC to 6 GHz is designed based on the coaxial structure. According to circuit principle and impedance matching of the transmission line, the device adopts the taper transition structure between the N connector and circular coaxial connected, which achieves the advantages of good impedance matching. The device is simulated by the CST software, and has been fabricated and measured. The simulated results show that S11 is better than –10 dB in the frequency range of DC-6 GHz. Due to the machining error, test results are slightly biased at individual frequencies, which have good consistency with the simulated results and demonstrate the desirable transmission performance of the radiation device. The design has great application value in electromagnetic radiation system.
