Surface-mount type antenna and antenna apparatus

A surface-mount type antenna comprising:

• a base body made of a substantially rectangular parallelepiped dielectric or magnetic material;
• a feeding terminal formed at one end side part of one side surface of the base body;
• a ground terminal formed at another end side part of one side surface of the base body;
• and
• a radiating electrode, to one end of which is connected the ground terminal, disposed such that its other end extends from the other end side part of one side surface, through the other end side parts of one principal surface and another side surface of the base body, to the one end side part of the other side surface, then turns to one end side part of one principal surface so as to extend farther toward the other end side part of one principal surface, and is eventually formed into an open end facing substantially perpendicularly with a midpoint of the other end side part of one principal surface,
• wherein the feeding terminal is so disposed as to extend from the one end side part of one side surface to the one end side part of one principal surface, and has its open end arranged in proximity to the radiating electrode.
