针对共面波导弯曲结构传输损耗较大的问题,提出了一种改进弯曲结构。该结构引入非对称共面波导弯曲结构以及相应的转换单元,解决了传统共面波导弯曲结构中容易激发奇模信号的问题。结合使用频域和时域的有限差分方法,对弯曲结构的传输系数进行了计算。理论分析和测试结果表明改进后的弯曲结构有效地抑制了奇模信号的传输,降低了共面波导弯曲结构的传输损耗。改进后的弯曲结构具有结构设计简单、易于加工的特点。
Aiming at the problem of large transmission loss of coplanar waveguide bending structure, an improved bending structure is proposed. The structure introduces an asymmetric coplanar waveguide bending structure and a corresponding conversion unit, which solves the problem of easily stimulating odd-mode signals in the traditional coplanar waveguide bending structure. Combined with the finite difference method in frequency domain and time domain, the transmission coefficient of curved structure is calculated. Theoretical analysis and test results show that the improved bending structure can effectively suppress the transmission of odd mode signals and reduce the transmission loss of the CPW structure. The improved curved structure has the characteristics of simple structure design and easy processing.
