Abstract:
A surface-mount type antenna comprising:a base body made of a dielectric or magnetic material having a substantially rectangular solid shape; a feeding terminal formed at one end of one side surface of the base body; a ground terminal formed at another end of the one side surface of the base body; a radiating electrode which has its one end connected to the ground terminal, the radiating electrode being disposed helically across the surfaces of the base body in such a way that it extends from the one side surface, across one principal surface, another side surface which is opposite to the one side surface, and another principal surface which is opposite to the one principal surface, and then returns to the one side surface and further extends, through the one principal surface, toward the one end of the one side surface; and a wide-area portion, wherein another end of the radiating electrode extends from the one principal surface, through the other side surface, toward the other principal surface, so as to form the wide-area portion facing the feeding terminal.
