Reconfigurable Compact Phased-Array Antenna for Scalable Wideband Operations

In the Phase I program, Omega Optics, Inc. will demonstrate a reconfigurable compact phased array antenna for scalable, wideband operations in X through Q frequency bands. The system architecture of the antenna is based on three-dimensional (3-D)integrated thin-film waveguide true-time-delay (TTD) lines. The proposed RF signal distribution network is highly favored in the field environment and can easily be scaled up for high-demanding performance upgrade. The device is unique in that it coversthe TTD range of , as well as coupling waveguides in adjacent layers. Packaging is greatly simplified, and the layered integration of the waveguides offers greater compactness than any other known geometry. Multifunction or configurability will be achievedthrough significant hardware reduction architecture. The proposed architecture would ultimately create a deployable all-optical TTD platform that can be tuned across multi-band. The photonic module will be developed under the highly scalable architecture.It maximizes the advantages of photonics with an improved performance at a reduced cost. The technology developed can also be directly employed in high bandwidth or cellular service satellite communication systems, such as direct TV, ICO, or mobilsat.
