A compact, low profile electronically scanned antenna module is provided. The antenna module includes a multi-layer antenna integrated printed wiring board (AiPWB) that includes a radiator layer on a front surface. The radiator layer includes a plurality of RF radiating elements. The antenna module additionally includes a plurality of radiator electronics modules orthogonally connected to a back surface of the AiPWB. The electronics modules are interconnected with radiating elements through the AiPWB and include a plurality of beam steering electronic elements mounted to a multi layer conformable substrate. The orthogonal connections allow the antenna module to have outer dimensions that are substantially equal to the dimensions of a perimeter of the AiPWB. Additionally, frequency and scanning angle requirements of the antenna module can be increased by merely increasing the length of the electronics modules in the orthogonal direction to allow for additional beam steering electronic elements needed to accommodate the increased frequency and scanning requirements.

An antenna module for an electronically scanned phased array antenna is provided. In various embodiments, the module includes a transmit/receive (T/R) module layer including a plurality of T/R modules. The module additionally includes an external phase shifter layer that includes a plurality of sets of secondary phase shifters. Each secondary phase shifter set is associated with a specific one of the T/R modules. Furthermore, the module includes a horn antenna layer having a plurality of antenna horns. The horn antenna layer is positioned between the T/R module layer and the phase shifter layer such that each horn is aligned between one T/R module and the associated one of the sets of phase shifters.
