This project aims to investigate the design of a broadband ?photonic antenna? for airborne radar warning and electronic countermeasure systems. The project will investigate the development of a suite of printed antennas that cover bands in the range from 2-40 GHz realised on a single substrate. Nesting these antennas to reduce system size, and integration of this module with a custom optical modulator array and RF signal combiner will be investigated. The resulting broadband antenna suite with photonic interconnect will require minimal fabrication and packaging resources, and will thus be an economically viable photonic solution for practical defence systems.Read moreRead less
