Fixing structure to enhance the mechanical reliability of plate slot array antenna based on SIW technology
This disclosure is directed to techniques to improve the mechanical reliability and strength of slot array antennae created using printed circuit board (PCB) technology. In some examples, a multi-layer PCB may have a limit on the length and width dimensions. Therefore, a larger slot array antenna may require two or more PCBs to create the full size of the antenna. This disclosure describes techniques to securely connect the two or more PCBs to withstand environments where the slot array antenna may be placed under mechanical stress, such as vibration. A PCB based antenna may define the walls of radiating waveguides with vias between the layers of the PCB. Mechanical fasteners may pass through some of the existing vias to secure the PCB to a support structure, such as a feeding waveguide, as well as to secure one PCB to other PCBs.
