Abstract
An antenna device that can be housed within a small portable radio receiver can be obtained by miniaturizing a small loop antenna. A small antenna device is formed by connecting first ends of first and second spiral conductors to a feed portion and a short circuit portion, respectively, of a grounding conductor, and connecting the second ends of these first and second conductors with a third conductor having a specialized, nonlinear shape and being substantially perpendicular to respective axes of the first and second spiral conductors.
