Abstract
An antenna comprising a laminate of dielectric ceramic layers each provided with electrode patterns, the laminate comprising a first terminal electrode connected to a feed line and a second terminal electrode for grounding on the lower surface, a radiation electrode on the upper surface or on a layer near the upper surface, and a coupling electrode between the lower surface and the radiation electrode; the coupling electrode being connected to the first terminal electrode through via-holes; the radiation electrode being connected to the second terminal electrode through via-holes; and the coupling electrode being partially opposite to the radiation electrode in a lamination direction to form a capacitance-coupling portion.
