摘要: An antenna is provided for GNSS and other applications includes an adjustable-height vertical support PCB mounted on a ground plane mounting crossed-dipole radiating arm element assembly. The gain pattern of the can be varied by constructing with different heights or adjusting height in field. Vehicles significant pitch roll low-horizon tracking capability providing high-profile configuration. Alternatively, low-profile configurations provide steeper rolloff at horizon maximal multipath rejection high accuracy. droop angles elements are also adjustable varying beamwidth. A matching phasing network connected to provides relatively constant input impedance various configurations. Alternative aspects invention have planes.
