Military UHF body-worn antennas for armored vests

In this paper, we present new body-worn antennas specifically designed for armored vests used by the military and law enforcement agencies. Typically, these vests have hard ceramic reinforced plates protecting the abdomen. The proposed antennas are mounted on these plates. New designs are shown for front, back and side armor plates and the simulations are validated using measurements. A diversity study is also performed to assess practical performance.
