Abstract
A multi-beam phased array antenna architecture includes a plurality of antenna modules, stacked together in a side-by-side relationship. Mutually adjacent edges of the modules have antenna elements that form a two-dimensional antenna array as a result of the stacking of the antenna modules. Opposite sides of an antenna module are tray-configured and contain amplifier modules coupled to the antenna elements, and to ‘vertical’ microstrip layers on undersides of double-sided printed wiring boards. Outersides of the double-sided printed wiring boards contain ‘horizontal’ microstrip layers, one for each beam, to which multiple beam-associated phase shift circuit elements for each antenna element on the module are ported. The phase shift circuit elements are also coupled by conductive vias to the first microstrip layers. The second microstrip layers are coupled to connectors along second edges of the modules for engagement with beam signal network modules.
