Problems solved by technology

There are many forms of conversion between rectangular waveguide and planar transmission line. The commonly used ones are mainly waveguide-ridge waveguide-microstrip transition, waveguide-microstrip probe transition and waveguide-probe-microstrip transition. These traditional microwave transition structures are difficult to integrate with on-chip circuits. The probe test structures (pads) are directly interconnected
