SBIR-STTR Award

The objective of the Phase 1, SBIR Topic A04-005, "Adaptive Bandwidth High Power RF Antennas," is to develop a broadband (a minimum of 2:1, up to, say, 6:1 or even 10:1 bandwidth) high gain (12 dBi minimum), operating in the HF/VHF and VHF/UHF bands, high power (300 KW at a 50% duty cycle) antenna. The maximum customer preferred size (VHF/UHF) is 1.2 meters diameter and 2 meters long, maximum. For the lower frequency (HF/VHF) of operation the maximum size is 2 meters in diameter and 3 meters long

The objective of the phase 1 and 2 SBIR Topic 04-005, ìAdaptive Bandwidth High Power RF Antennaî program is to develop miniaturized, high power antenna over the customer desired frequency range of 100 MHz to 95 GHz, with typical bandwidths of 2:1, up to 10:1 with a high gain of 12dBi (minimum) and operating under high powers of possible 2? Megawatts at the lower frequencies and 100 Kilowatts at the millimeter wave frequencies. At certain frequencies and operational scenarios the ranges to the desired targets maybe small and thus operation in the near non-radiating field maybe reality. Another major program objective is the achievement of high operation power effects even in the non-radiating near field. The radiating process will be optimized, as well a achieving a reduction of the near field effect.
