Abstract :
The helical antenna has been regarded as broadband circular polarized antenna structure with relatively high gain. The performance of the helix can be improved by loading with a dielectric resonator, DR εr>1, so as to extent the length of helical arm and reduce the axial ratio. In this paper, the helix element has been investigated and developed for use as the antenna for low or medium Earth orbit satellite mobile communication systems, such as IRIDIUM, GLOBALSTAR, etc
