Abstract :
In this paper a new class of helmet antennas with omnidirectional pattern has been developed. Its radiation performance is considerably superior to that of conventional resonant whip antennas for terrestrial field applications over a much wider bandwidth and with more stable connectivity regardless of the wearer´s body movement and orientation. In addition, the helmet antenna has other practical advantages over the whip antenna. Thus, this helmet antenna appears to be a viable solution for many real-world applications
