Simple Analysis of a Slot and a Reflection-Canceling Post in a Rectangular Waveguide Using only the Axial Uniform Currents on the Post Surface
Summary :
An element consist of a slot and a post is designed for canceling the reflection in a rectangular waveguide by the method of moments. For reducing the computation time in practical design of the element with a wide range of coupling strength for an array, only the axial uniform currents on the post surface are considered. This approximation is valid when the post for reflection-canceling is far enough from the slot. The post location is determined by this simple analysis for both transverse and longitudinal slots with typical coupling strength. Measured results using 4 GHz-band standard waveguides reveal that the assumption of uniform line currents on the post surface is acceptable. The design is further extended to demonstrate its applicability to a practical array design by considering a wide range of coupling strength.
