衬底集成波导具有低损耗和高集成度的优点，在现代微波和毫米波电路的设计中得到了广泛的应用。但在低微波波段存在体积大的缺点。近年来，提出了一种新型的半模衬底集成波导（HMSIW），它在保持SIW良好性能的同时，尺寸减小了近50%。到目前为止，还没有HMSIW多路功率分配器的报道，主要是由于其本身的不对称性。本文提出了一种新型的HMSIW t型结，使HMSIW多路功率分配器的设计成为可能，并提出了两类多路功率分配器。仿真结果与实测数据吻合，表明该方法可用于平面阵列天线的有效馈源设计。
With merits of low loss and highly integration, substrate integrated waveguide (SIW) has been widely used in the designs of modern microwave and millimeter circuits. However it suffers from the big size in low microwave band. Recently, a novel half mode substrate integrated waveguide (HMSIW) has been proposed, which keeps the good performance of SIW with a nearly 50% reduction in size. So far, no HMSIW multi-way power divider is reported, mainly because of the unsymmetry of itself. In this paper, a new HMSIW T-junction is proposed, with which the design of HMSIW multi-way power divider become feasible, and two classes of multi-way power dividers. The agreement between measured data and simulated results shows that HMSIW can be used to design effective feeds for planar array antenna.
