A circular patch antenna for surface oriented radiation is disclosed. The disclosed antenna includes: a substrate; A circular patch disposed on the substrate; A ground plane formed under the substrate; A power supply member positioned between the circular patch and the ground plane and providing a feed signal to the circular patch in a coupling manner; And a plurality of via pins formed in a structure that penetrates through the substrate in combination with the ground plane and is arranged around the circular patch. The disclosed antenna has a simplified structure and can realize a surface-oriented radiation characteristic, and has an advantage that an impedance matching can be easily performed.
