论文摘要
详细研究了间隙波导技术和传统的共面波导的结合，并首次在实验中进行了研究。这条新型的超材料传输线以三种不同的配置表示，并提供了宽带操作，低损耗和低分散特征。通过有限元方法模拟提供并验证其特征阻抗和有效介电常数的分析表达式。用本本型求解器分析线的损失和分散。拟议的线防止了操作带中基板模式的传播，同时由于E-Field浓度较高，因此降低了线路的介电损失。此外，其共面布局有助于积极组件的整合。因此，它被认为构成了开发更高效的毫米波系统的潜在关键要素。
A combination of gap waveguide technology and the traditional coplanar waveguide is studied in detail and demonstrated experimentally for the first time. This novel metamaterial transmission line is presented in three different configurations and offers a broadband operation, low loss, and low dispersion characteristics. Analytical expressions for its characteristic impedance and effective permittivity are provided and validated by Finite Element Method simulations. The loss and dispersion of the line are analyzed with an Eigenmode solver. The proposed line prevents the propagation of substrate modes in the band of operation at the same time it reduces the dielectric loss in the line due to a higher concentration of the E-field over the air. Moreover, its coplanar layout facilitates the integration of active components. As such, it is considered to constitute a potential key element in the development of more efficient, millimeter wave systems.
