Ultra-wideband radio frequency vest antenna

The ultra-wideband radio frequency vest antenna is the result of the research efforts to develop an antenna system to support the Joint Tactical Radio System (JTRS) currently being procured by the United States Department of Defense. The JTRS is an ultra-wideband radio system that is expected to operate in the 2 MHz to 2000 MHz frequency range. It is a frequency agile system that requires an equally responsive antenna system. The operating spectrum of the radio has been determined to be effectively covered through the use of three separate antennas. The frequency divisions are 2 to 30 MHz, 30 to 500 MHz, and 500 to 2000 MHz. This paper focuses on the 30 to 500 MHz frequency range in support of the dismounted Marine or soldier in all combat environments.
