PROBLEM TO BE SOLVED: To provide a surface mounted patch antenna having a feeding portion at a predetermined position in an x direction and a y direction from a center position of a radiation electrode, capable of performing surface mount without making a feeding pin to pass through a mounting substrate etc. SOLUTION: The radiation electrode 2 is provided to a surface which is a plane of a dielectric substrate 1, and a ground electrode 5 is provided at a back surface which is opposing to the plane of the dielectric substrate 1. One end portion 3a of the feeding pin 3 is connected to the radiation electrode 2, and the other end portion 3b is extracted to the back surface side through a through hole 1a provided on the dielectric substrate 1. At the back surface side of the dielectric substrate 1 of this through hole 1a, a recess portion 1b having the mostly same center as the through hole 1a and an inner circumference larger than a diameter of the through hole 1a is to be formed. The other end portion 3b of the feeding pin 3 is to be formed on the nearly same plane as an exposed surface of the ground electrode 5 to be provided on the back surface of the dielectric substrate 1, and is to be formed as the configuration to be directly mounted on the surface of the mounting substrate.
