Abstract : The objective of the research documented in this report was to determine if the accurate time delay and the broad bandwidth of fiber optics could be exploited to construct a time delay phasing device for a microwave antenna. Time delay phasing of microwave antennas is highly desirable because there is no coupling between the signal bandwidth and the antenna beam angle for a time delay antenna. This enables radiation of broad bandwidth signals necessary for close range resolution at precise angles from a phased array mirowave antenna.
