The prototype design parameters apply to the W-band, i.e. 75-110 GHz, but can be scaled for other frequency bands associated with waveguides with the same 2:1 aspect ratio. These components are designed for an Over-The-Air (OTA) power-combining setup, which will be expanded to include a Rotman lens module for beam switching. An OTA transmission experiment is carried out with the aforementioned components to examine the performance at a system level.enWaveguide componentsW-band transmitterOTA power-combiningconference paper
