ANTENNA FOR RECEIVING GPS SIGNALS

摘要

PURPOSE: A GPS receiving antenna is provided to reduce a position measurement error by minimizing the receiving rate of multipath propagation while improving the receive sensitivity of a GPS signal. CONSTITUTION: A dielectric body(210) forms a ground plane in lower-part. A plurality of patch radiation elements(230) is arranged on the upper side of dielectric body in a row. A slot(231) is formed in the center of the patch radiation element in the oblique direction of an arrangement direction shaft. A feeding line(250) is electrically connected to the patch radiation element. The feeding line comprises first feeding lines(251,253,255). The width of one side of the patch radiation element is smaller than the width of the other side of the patch radiation element.
