The paper describes the development of a flexible wearable antenna used in military and police work. The design is based on numerical simulations using commercial software. Simulations taking into account the curved-surface profile of the antenna and differently sized human bodies are presented. Experimentally obtained return loss and radiation patterns are shown in comparison with the computed results. Measured return loss better than 7 dB has been achieved across the frequency band of 360-460 MHz. The superiority of the antenna with respect to conventionally used antennas in the abovementioned applications is demonstrated.
