Abstract
A circularly polarized ceramic patch antenna having an extended ground for a vehicle is provided. The extended ground is formed under a patch antenna, has a predetermined thickness, is formed of a metal conductor having the same shape as the patch antenna, and is electrically connected to a ground plane formed on a board. The thickness of the extended ground is adjusted, so that it is possible to adjust radiation efficiency of the ceramic patch antenna that operates at a specific frequency band. Thus, the ceramic patch antenna has the effect of improving directionality of a radiation pattern formed in a direction parallel to the ground plane, and the effect of reducing a null point caused by a field effect to increase an antenna gain thereof.
