Double-Ridge Five Port Power Splitter Using Gap-Waveguide

In microwave engineering, waveguides are a key component when transmitting high frequency waves with low losses. However, these are inherently bulky in size and difficult to integrate with other microwave components. Gap-Waveguides are a good solution for mm-wave frequencies since they are easier to integrate with other components and easier to fabricate since there is no need for a complete physical shield. This work uses gap-waveguide technology to develop a 4:1 power splitter network that can operate from 20 GHz to 40 GHz with very low losses and less than 2:1 VSWR.
