An integral phased array module may include a substrate and a radio frequency (RF) element provided in relation to the substrate. The RF element being configured to at least one of transmit and receive RF signals. The RF element includes a footprint of a particular size and shape with respect to the substrate and the substrate is sized to accommodate the footprint of the RF element. The integral phased array module may also include an optical function element configured to perform an optical function. The optical function element is located relative to the RF element on the substrate for integrating multi-band functionality into a single aperture.
