A DIRECT FEEDING TYPE PATCH ANTENNA

摘要

Disclosed herein is a direct feeding type patch antenna. The direct feeding type patch antenna according to the present invention comprises: a feed element 110 having direct feeding points 118 formed radially in opposite perpendicular directions to one another from a feeding central portion 120; four direct feeding cylindrical pillars 130 electrically connected at one ends thereof to the direct feeding points 118; and a radiation patch 140 disposed opposite to the feed element 110 and electrically connected to the other ends of the direct feeding cylindrical pillars 130, for allowing an electrical signal to be directly fed thereto. The direct feeding type patch antenna further comprises a coupler made of a ceramic material. According to the present invention, it is possible to implement a patch antenna which has a high gain and an improved axial ratio bandwidth, and is small-sized.
