A surface mounted antenna according to the present invention includes a dielectric block 11, a radiating electrode 12 formed on one of a main surface 11a of the dielectric block 11, a ground electrode 13 formed on the other main surface 11b of the dielectric block 11, and a feed electrode 14 formed on a side surface 11c of the dielectric block 11 and electromagnetically coupled with the radiating electrode 12. In the present invention, since the feed electrode 14 is formed on the side surface 11c of the dielectric block 11, the size of the main surface 11a of the dielectric block 11 can be made smaller than that of the conventional dielectric block. Accordingly, since further miniaturization can be realized, when the dielectric block 11 is mounted on a printed circuit board or the like, the mounting area can be reduced as compared with the conventional dielectric block.
A surface mounted antenna comprising a dielectric block, a radiating electrode formed on a one main surface of the dielectric block, a ground electrode formed on the other main surface of the dielectric block, and at least one feed electrode electromagnetically coupled to the radiating electrode formed on a surface different from the one main surface and the other main surface of the dielectric block, wherein the feed electrode has a linear end facing to the radiating electrode, the linear end substantially parallel to and substantially ending at an edge of the one main surface.
