| 中文摘要: |
| 根据波导定向耦合器原理，设计了一种太赫兹频段，采用非对称十字形孔耦合的矩形波导定向耦合器。通过优化波导结构和十字形耦合孔参数，在WR4波导频段内，实现了稳定的耦合平坦度、良好的方向性和工作带宽。仿真结果表明该型波导定向耦合器耦合度稳定在-19.9dB~-22.0dB之间，方向性优于32dB，相对工作带宽为40%。 |
| 英文摘要: |
| A terahertz cross-guide waveguide directional coupler with unsymmetrical crossed slots is proposed in this paper. By adjusting the basic structure of rectangular waveguide and optimizing the parameters of the crossed slots, this waveguide directional coupler realizes a stable coupling flatness, a good directivity and the working bandwidth within the WR4 standard waveguide. The simulation results present good coupling flatness value from -19.9dB~-22.0dB, the isolation value is greater than 32 dB, and the relative working bandwidth is 40%. |
