Antenna Technologies for Achieving Spectrum Dominance
October 30, 2018 @ 6:00 PM - 8:00 PM
Co-sponsored by: Association of Old Crows – Mile High Chapter
Recent developments in materials, solid-state and digital electronics have shown that the new transmit and/or receive systems capable of carrying out smart and adaptable spectrum sensing and control functionalities through the millimeter waves are now feasible. In this talk, we discuss a few important aspects of antenna systems developed for the above stated mission. First we review a systematic development of components, devices, and antenna subsystems aimed for high-power applications in 0.5-110GHz range. Starting from a basic transmission line, we discuss the design and performance of new antennas, dividers, hybrids, couplers, twists, etc., as well as more complex systems including ortho-mode transducers. While this research is aimed for space-constrained platforms, the results can be successfully utilized across different systems. Next, we show a family of front-end subsystems designed and fabricated for wideband spectrum sensing missions through 110GHz. Single-aperture analog and digital beam-formed antennas, Butler matrix, Rotman and Luneburg lens arrays are built using conventional and emerging techniques and their superior wideband, low-loss performance is experimentally demonstrated. Low-cost prototyping for assessing the performance of emerging front-end systems is also discussed.
