Design of Open Ended Quadfilar Helical Antenna for 2.4 Ghz
Helical antenna can be design as a monofilar helical antenna or multifilar helical antenna. It is having two radiation modes. In normal mode helix, the direction of radiation is normal to the axis of helix and in axial mode helix, the direction of radiation is in the axis of helix. There are two types of helical antenna (monofilar helical antenna and multifilar helical antenna). In this paper, the design of open ended Quadfilar Helical Antenna (QHA) is proposed.
