摘　　要：提出了一种新型折叠间隙单元结构,相比传统平面间隙单元结构,其能够实现阻带下截止频率和阻带上截止频率分别朝低频和高频移动,实现宽阻带的性能。基于所提出的新型折叠间隙周期单元结构构建折叠脊间隙波导传输结构,并基于该折叠脊间隙波导设计了一款工作于Ka波段的Gysel功分器。提出了一种微带线至该折叠脊间隙波导的过渡转换,用于实现和有源芯片的互连集成以及测量,并对所提出的结构进行了加工、装配和测试,测试结果和仿真结果吻合较好。测试结果表明,该Gysel功分器能够在Ka波段(30~42 GHz)实现等功率分配和15 dB的端口隔离。A novel folded gap unit cell was proposed in this paper.Compared with the planar traditional one,the lower and upper cut off frequencies move towards lower and higher frequencies,respectively,obtaining a wider stopband bandwidth.Then,a ridge gap waveguide transmission structure is constructed based on the proposed folded gap periodic unit cell,and a Ka-band Gysel power divider is proposed using the ridge gap waveguide.Moreover,a transition from the microstrip to such a ridge gap waveguide is also proposed in this paper for the integration and measurement with other chips.Finally,the proposed Gysel power divider is fabricated,assembled,and measured.The measured results show a good agreement with the simulated ones.It shows that the Gysel power divider achieves an equal power division ratio in Ka-band(30~42 GHz),and the isolation between the two output terminals is about 15 dB.
