为解决准横电磁(TEM)模波导工作带宽较窄的问题,提出采用金属贴片电磁带隙(EBG)结构在金属波导中创建准TEM波.通过理论分析和数值计算,研究金属贴片EBG结构创建准TEM波导对展宽带宽、改善传输特性和增强准TEM波电场分布均匀性的作用.模拟结果表明,在频率14 GHz附近,金属贴片EBG将TE10模成功转换成准TEM模,转换带宽达到1.7 GHz,且在波导横截面83.9%的面积上电场分布均匀性达到84.7%.

To solve the narrow operation-band of the electromagnetic bandgap (EBG) waveguide, a quasi transverse electromagnetic (TEM) mode waveguide using the metal-patch EBG structure as sidewall is proposed in this paper. Theoretical analysis and numerical calculation show that broader bandwidth, better transportation property, and more uniform electric field distribution of the quasi-TEM mode can be reached. Simulation results using Ansoft HFSS indicate that the metal-patch EBG structure can convert TE10 mode into quasi-TEM mode in the central frequency of 14 GHz with a bandwidth of 1.7 GHz and the uniformity of electric field distribution reaches 84.7% in 83.9% cross section area.-
