Abstract: The objective of the proposed Phase I effort is to investigate the feasibility of a broadband High Power Radio Frequency (HPRF) antenna system that is capable of handling power of 1000 MW over a wide bandwidth including mid VHF to L-Band. It is desirable that the antenna occupy minimal volume when deployed and especially while stowed. The objective is to not only expand the frequency of operation and gain of the high power antenna, but that the antenna occupies minimal space such that it can be practically fielded aboard a seaborne platform. The directional antenna gain objective is +10 to +15 dBi. For applications of this technology beam steering is also of importance based on the expected concept of operation. FIRST RF proposes a unique solution that consists of a high power feed with material treatments and a beam collimator for directionality and steering capability.
Benefits: Because of the improved form factor and capability provided by our steering solution, the recent advancements in high power radio frequency generators can be harnessed for a variety of applications both military as well as commercial. The military applications include fielding aboard seaborne platforms with limited deck space and room for antennas. The antenna requires minimal real estate improving integration by allowing for various installation locations that are best suited for on-deck performance. One such platform that could be of significant operational benefit are the Littoral Combat Ship class of relatively small surface vessels intended for operations close to shore. Integration on this class of vessel provides this technology the benefit of operating within range of both sea vessels as well as land based targets as well. The technology can be applicable to ground vehicles as well as the antenna structure is independent of the geometry of the vehicle. The commercial benefits include law enforcement, homeland security, as well as border patrol, and Coast Guard.
