Understanding the Fundamentals of Double Ridge Waveguide Technology

• The Engineering Principles Behind Ridge Waveguide Design

The Double Ridge Waveguide Transition represents a significant advancement in transmission line technology, built upon sophisticated electromagnetic principles. At its core, the component features two ridges extending inward from opposite walls of a rectangular waveguide, creating a distinctive cross-sectional profile that fundamentally alters how electromagnetic waves propagate through the structure. This specialized geometry serves a crucial purpose: it effectively lowers the cutoff frequency while maintaining the same outer dimensions as conventional rectangular waveguides. The physics behind this design leverages the concentrated electric field between the ridges, which enables a wider operational bandwidth—often spanning multiple octaves—compared to standard waveguides that typically operate within a 1.5:1 frequency ratio. Advanced Microwave Technologies Co., Ltd. has perfected this design, manufacturing Double Ridge Waveguide Transitions that maintain exceptional field distribution characteristics across frequencies ranging from 1 GHz to an impressive 110 GHz.
