Abstract
The design of a Global Navigation Satellite System (GNSS) antenna requires consideration of a range of characteristics including, for example, the ability for tracking satellites at low elevation, phase centre variation (PCV), antenna efficiency and impedance, axial ratio and up-down ratio (UDR), antenna bandwidth, etc. whilst also providing a light weight, compact and robust form factor. For rover applications this becomes particularly important when the satellites being accessed may be at low elevations where prior art GNSS antenna exhibit poor performance. To address this a GNSS antenna is provided comprising a domed array of opposed metallized antenna elements which are indirectly coupled via a pair of dipoles to the feed network thereby avoiding the difficulties associated with direct electrical connections of feed circuits to antenna elements.
