Patent attributes
An antenna array system can include a plurality of sheet metal structures arranged substantially parallel to one another. Each sheet metal structure can include a row of antenna elements and the plurality of sheet metal structures can form an array of antenna elements. The antenna array system can include a plurality of printed circuit boards (PCBs) each of which is mechanically and electrically coupled to a respective sheet metal structure. Each sheet metal structure extends beyond the PCB to which it is mechanically coupled. The antenna array system can include at least one electromagnetic shielding structure configured to electromagnetically shield one or more circuit components from the array of antenna elements. The antenna array system can also include one or more alignment structures configured to provide mechanical rigidity to the array of antenna elements and to allow for spacing between pairs of adjacent sheet metal structures.
