To provide a surface mount antenna which reduces the null point in the directional characteristic, satisfies omnidirectivity and bandwidth, is small with high performance, and an antenna device mounted with the surface mount antenna.
In this surface mount antenna in which radiating electrodes are arranged on a dielectric or magnetic base body, the surface mount antenna has a main radiating electrode provided on the top face of the base body and a sub radiating electrode provided on the bottom face of the base body, respectively, and a connection electrode provided on a side so as to connect the main radiating electrode and the sub radiating electrode. The connection electrode has a feeding point at its connection part with the sub radiating electrode and is horizontally and asymmetrically connected with respect to the center of the side of the base body.
