Vacuum Waveguide Coupling for Fast PCB Electromagnetic Transfer

The patent replaces the traditional mechanical screw connection system with a vacuum-based holding system. The vacuum holder generates a vacuum between its holding surface and the PCB surface, creating sufficient holding force to secure multiple waveguide flanges without requiring screws. This substitution eliminates the time-consuming screw tightening operation while maintaining reliable, leak-less transmission of electromagnetic waves.

The vacuum holder serves multiple functions simultaneously: it mechanically holds multiple waveguide flanges in position, provides alignment reference surfaces for precise positioning, and creates a sealed vacuum chamber for leak-less transmission. This multi-functionality consolidates what would otherwise require separate alignment fixtures and multiple screw connections into a single integrated component.

The vacuum holder is designed with multiple holding surfaces that can simultaneously secure multiple waveguide flanges of different types and standards. Each holding surface provides alignment references and vacuum sealing, allowing the single vacuum holder to perform the function of multiple separate connection devices, thereby increasing adaptability without proportionally increasing mounting effort.

The patent combines multiple waveguide flange holding functions into a single vacuum holder body. Instead of using separate screw connections for each waveguide flange, the vacuum holder integrates multiple holding surfaces that can accommodate various waveguide standards simultaneously, merging what would be multiple independent mounting operations into one vacuum-based securing action.
