Abstract
A novel substrateless power amplifier module realized by ridge gap waveguide (RGW) technology is proposed in Ka-band. Up to our knowledge, this is the first time that an active device is directly integrated with an RGW structure. No substrate is used in the RF section of the implemented power amplifier and the whole structure is made by machining a piece of metal. The amplifier was made of two pieces and was easily assembled without needing a precise contact between the two sections. The cavity resonance of the amplifier is suppressed using a pining structure. The fabricated amplifier module is self-packaged and does not need any packaging. It is shown that the simulated and measured results...

Abstract
A half power divider using ridge gap waveguide technology is realized in millimeter wave frequencies. By machining a piece of metal the divider was fabricated. There is no need to an electrical connection between the divider constitutive parts. The fabricated divider is self-packaged. Cylindrical pins are used in the divider structure for ease of fabrication. Low loss power division and good isolation between ports is measured. Also the measured impedance matching of the divider ports is acceptable. Good agreement between the simulation and measurement is achieved. © 2016 IEEE
