Convex GNSS Reference station antenna

Novel Convex Reference station antenna with advanced functionality versus common Choke Ring antenna has been developed. Pins impedance structure is used instead of common choke grooves providing with more consistent frequency response. Convex impedance ground plane provides with less gain pattern roll-off from zenith to horizon and better rejection of multypath signals. Novel full spectrum GNSS antenna element as a spherical array of convex patches has been built. Performance characteristics are shown.
