Abstract:
1. A patch antenna comprising: a dielectric substrate, having a first face which is formed with a cavity, and a second face opposite to the first face, the dielectric substrate formed with a substrate hole which connects the cavity and the second face; an antenna radiation electrode, comprised of a conductive film and formed on the first face of the dielectric substrate; a ground electrode, comprised of a conductive film, formed on the second face of the dielectric substrate and formed with a ground hole which is substantially concentric with the substrate hole and has a diameter larger than that of the substrate hole; and a feeding pin, one end of which is connected to the antenna radiation electrode and the other end of which is extended toward the second face of the dielectric substrate through the substrate hole and the ground hole, wherein the feeding pin includes a head portion provided at the one end and a rod-shaped body portion extending from the one end to the other end; and the head portion is buried in the cavity, wherein the cavity is filled with solder, and wherein the solder has a convex portion which is protruded from the first surface and is electrically connected to the antenna radiation electrode.
