This paper presents the recent research of the COMbatWear INtegration (COMWIN) RF Vest antenna presentedat MILCOM2000. This version of the ultra-widebandVHF/UHF (30 MHz to 500 MHz) vest antenna, designatedas MK-III, is integrated into the existing dismountedMarine/Soldier Kevlar flak vest and has no visualsignature. This antenna is one of the three COMWINantennas developed at the Naval Postgraduate School(NPS) for the Joint Tactical Radio System applications. The improved RF Vest (MK-III) was designed usingAnsoft’s High Frequency Structure Simulator (HFSS)software. This design accounts for the operator wearingthe flak jacket, the MOLLE pack system, and the radio(radio dimensions based on SINCGARS man-portableradio). Several prototypes have been built at NPS andexhibit encouraging agreement with computer simulations.
