Ultra-Wideband (UWB) systems are currently needed to serve a variety of Navy and Air Force missions, including tactical communications and jamming. One of the components of UWB systems that requires much careful thought and innovation is the antennas, since most of the classical antennas are useful only for more narrow bandwidths.A class of antenna known as Impulse Radiating Antennas (IRA) have received considerable attention. These are composed of a TEM feed plus either a reflector or lens to focus the aperture. Such antennas have already demonstrated two decades of bandwidth, from about 300 MHz to 30 GHz.In cases where multiple antennas are necessary, wideband antennas can serve as the single antenna for multiple missions. This can reduce the total number of antennas that are necessary to support an operation. This could be important in situations requiring man-packable systems. It could also be of importance in situations where aperture area is limited on a military asset.We propose developing a Collapsible Multifunction Impulse Radiating Antenna. Such an antenna will be easily transportable and quickly set up. It will have an effective bandwidth between 80 MHz and 2 GHz. It will be able to switch between a high-gain narrow beam and a broader beam pattern with lower gain. The reflector will be collapsible and transportable.
