Wideband 2-plane Short-slot Coupler Using Frequency Shift of Propagating Modes

摘要

In this paper, a wideband design of the waveguide 4×4- way short-slot 2-plane coupler is presented. Using frequency shift of propagating modes, 4×4-way short-slot 2-plane couplers acquires 6% bandwidth. It makes to extend the application like Butler matrix and splitter/combiner network.
