Abstract
Embodiments of active array antennas are generally described herein. Other embodiments may be described and claimed. In some embodiments, a reflect array antenna includes an array of rectangular monolithic sub-array modules arranged in a non-uniform pattern to leave a plurality of rectangular gaps in the pattern. A DC feed pin located within each gap may provide DC bias current to the sub-array modules. The sub-array modules may be mounted on a heat sink in the non-uniform pattern. The heat sink may have holes aligned with the gaps to allow passage of the DC feed pins. In some embodiments, an array cooling assembly may be coupled to the back of the heat sink to cool the reflect array antenna with a coolant.
