Electronically Scanned Array (ESA) Antenna Transmit/Receive Module

Space-based radar (SBR) and mobile surveillance systems require effective integration of phased-array antenna modules for beamforming. This proposal in response to the SBIR phase I solicitation addresses reduction of components by combining desired performance features and integrates them on a Si-based wafer. Additionally, wafer scale antenna module (WSAM) includes integration of large number of antenna elements on the same substrate. Wafer scale integration objectives have been addressed by focusing on incorporation of interconnects and radio frequency active components, direct current, and control signals for an optimum power dissipation. The proposal predicts a 40X weight reduction and better than 37X volume reduction for beamforming module, while operating without a cooling system. Furthermore, integration of the antenna array with fully integrated electronics on a Silicon wafer enables removing connectors that cause serious insertion losses, hence, improving the signal-to-noise for more efficient transmission and less required sensitivity for signal receiver.
