Waveguide-to-Microstrip Adapter is a key component for high-efficiency mode conversion between waveguide (TE₁₀ mode) and microstrip line (quasi-TEM mode) in microwave and millimeter-wave systems. It is specially designed for integrating planar circuits (PCB) with waveguide systems, and widely used in radar, satellite communications, 5G/6G millimeter-wave applications, RF testing and other scenarios.
Core Principle and Structure
Mode Conversion: Converts TE₁₀ transverse electric wave in the waveguide to quasi-TEM transverse electromagnetic wave in the microstrip line. Low-loss and low-VSWR transition is realized through probe coupling, ridge waveguide tapering, impedance matching and cavity resonance.
