PERSONAL POSITIONING SATELLITE NAVIGATOR WITH PRINTED QUADRIFILAR HELICAL ANTENNA

摘要

navigation unit (10) for receiving navigation signals from a signal source, for example from global positioning satellites. Said navigation unit is designed to be mounted in the frame and connected to a remote antenna and fixed to act separately and independently using a helical antenna (14) mounted directly. The preferred antenna (14) includes antenna elements composed of a thin film of conductive material (50) printed on a flexible substrate (46) wound to give a tubular configuration.
