Abstract: A connecting system can couple two waveguides to one another, wherein each of the waveguides comprises a flange or a protruding rim. When the waveguides are connected together, the flanges can face one another in an adjoining arrangement. The connecting system can comprise two members, each having a groove, recess, or slot that receives a circumferential area of the adjoining flanges. The two members can be disposed on opposite lateral sides of the waveguides with each groove embracing a peripheral area of the adjoining flanges. A fastener or another apparatus can bring the two members towards one another, thereby causing the flanges to move deeper into the grooves. That is, the two members can clamp around opposing sides of the flanges. In response to the flanges moving deeper into the grooves, the sidewalls of the grooves can compress the flanges together to attach the waveguides to one another.

Abstract: A compact system can use modular components to enhance the isolation or quality of signals that an antenna array produces. The system can comprise an array of input coupler modules and an array of output coupler modules respectively on the input and output sides of a signal routing device. Each input coupler module can receive a signal from a specific element in the antenna array and can divide or split that received signal into a multiple signal components, such as seven. The signal routing device can route each of those signal components to a different output coupler module in the array of output coupler modules. Thus, each output coupler module can receive and combine multiple signal components, such as seven, from different input coupler modules. The signal routing device can include a readily manufacturable phase trimming section to compensate for phase mismatches.
