A Novel Broadband Dual Circularly Polarized GNSS Antenna

In this paper, an innovative antenna for positioning, surveying and navigation is described. It receives both the right-hand circularly polarized (RHCP) and left-hand circularly polarized (LHCP) signals simultaneously and with high isolation. The antenna covers all GNSS (Global Navigation Satellite Systems) frequencies in L band, shows excellent performance in open-sky environments and clearly detects signals which have been corrupted by diffraction and reflections. There are no such products on the market at the present time.
