Abstract :
A wideband conical printed tapering quadrifilar helical antenna for Global Navigation Satellite System (GNSS) is presented. By wrapping four printed tapering helical strips on the surface of modified hollow conical dielectric rod and using wideband network with stable amplitude and phase distribution to feed, the proposed antenna are effectively designed to achieve wide bandwidth, desired gain and wide angle axial ratio characteristics, which are mainly required for GNSS receiver, especially for measured receiver with high precision.
