Abstract
The planar inverted-F antenna includes a first substrate made of a dielectric material, a grounding electrode disposed on a first surface of the first substrate; an emitting electrode disposed to be opposite to the grounding electrode so as to sandwich the first substrate, wherein the emitting electrode has an S-shape, and has a short-circuiting point short-circuited to the grounding electrode at an edge portion thereof, and a feed point at which power is fed and which is located away from the short-circuiting point by a distance at which the characteristic impedance of the planar inverted-F antenna for electric waves with a certain design wavelength has a certain value; and a second substrate disposed to cover the entire emitting electrode together with the first substrate and made of a dielectric material.
