Linearly Polarised Normal Mode Helix Antenna at UHF-Band for Inter-Satellite Communication Application

In this paper, a light weight, linearly polarized normal mode helix antenna for inter-satellite communication application in UHF band is discussed. Near isotropic radiation pattern except along the boresight axis makes it suitable for inter satellite communication at shorter distances consuming low power. It has return loss better than 15dB and minimum coverage gain of -5dBi over ±50° with respect to axis perpendicular to boresight axis.
