Title:
SATELLITE NAVIGATION ANTENNA AND SATELLITE NAVIGATION TRANSCEIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/240792
Kind Code:
A1
Abstract:
Provided in the present application are a satellite navigation antenna and a satellite navigation transceiving device. The satellite navigation antenna comprises an incompletely symmetrical metal reflection ground plate and a passive antenna element that is located at the central position of the metal reflection ground plate, wherein the metal reflection ground plate is an axisymmetrical pattern that has two axes of symmetry, i.e. a short axis and a long axis, which are perpendicular to each other; and there are two gaps in the metal reflection ground plate in the direction from an end point of the long axis to the central position along the long axis, and the two gaps have the same shape and size, and the locations thereof are symmetrical along the short axis. By means of the technical solution, slotting in the direction of a long axis of a metal reflection ground plate, which is of an incompletely symmetrical shape, of an antenna can effectively improve the axial ratio performance and the 3db axial-ratio beam width of the antenna, and can improve the quality of the antenna receiving or transmitting a signal.
