SINGLE FEED WIDEBAND CIRCULAR POLARIZED PATCH ANTENNA

摘要

A broadband circular polarization patch antenna can improve the axial ratio bandwidth of the circular polarization by forming the upper patch on the one side of the lower part patch. The connector(170) is connected to one side of the earth plate(180). The dielectric substrate(110) is laminated on the other side of the earth plate. The lower part patch(130) of hexagon is laminated on one side of the dielectric substrate. Hole is formed in the lower part patch. The feeding point is formed inside hole. The single feeding probe(160) connects the feeding point and connector. The upper patch(120) of hexagon is laminated on one side of the lower part patch.
